While after 4.3, every other rogue will be sporting Cursed Vision of Sargeras (thank God for no Glaives transmog) and everyone else will be decked out in old tier gear, some will be looking for less flashy options. There are also people who don't have the time to grind old instances or put together mini-raids for bosses they can't solo.
Yesterday, someone posted a thread on the US General forum, asking people to show off their future transmog sets. As more of these threads start popping up, my guess is that even those who couldn't give a fig about the transmog feature may start getting interested, especially as some sets people put together look beyond awesome and bad-@ss, and include BoE pieces which don't require navigating old instances. This may come in particularly handy for folks who started playing in Wrath and never set foot in a BC heroic or raid (especially since until a while ago, BC heroics still required attunements). There may also be people who want to replace a particularly ugly piece, rather than an entire set.
So here are some suggestions for making money off transmogrification:
1. Visit your local AH and spend some time trying on gear, or search Wowhead for BoE green items per slot/armor class (e.g. cloth helms, uncommon, BoE, level required 60-70). These are some loose criteria for picking gear that you might be able to resell after the patch:
Helms
Helms are important because the vast majority of us are hiding the God-ugly helms we have to wear for stats. While some will go for flashy stuff, like old tier helms, some may be happy with a simple circlet which goes with everything. Here are some suggestions:
- anything that allows hair to show. Correction here: the hats I was thinking of tend to clip through my banker's hair for some reason. Could be a worgen problem.
- crowns and circlets. Examples:
- green - Arachnidian Circlet - Arachnidian Circlet - Item - World of Warcraft or Councillor's Circlet - Councillor's Circlet - Item - World of Warcraft
- white/gold/silver - Highborne Circlet - Highborne Crown - Item - World of Warcraft or Elegant Circlet - Highborne Crown - Item - World of Warcraft or Celestial Crown - Highborne Crown - Item - World of Warcraft
- blue - High Councillor's Circlet - High Councillor's Circlet - Item - World of Warcraft
- red/gold - Resplendent Circlet - Resplendent Circlet - Item - World of Warcraft
- burgundy - Starfire Circlet - Starfire Circlet - Item - World of Warcraft
- weird/funny. A good example would be Vindicator's Cap - Vindicator Cap - Item - World of Warcraft
- "character" hats. Examples:
- Black hat - Master's Hat - Master's Hat - Item - World of Warcraft
- Middle-eastern looking hat - Slavehandler Cap - Slavehandler Cap - Item - World of Warcraft
- Hoods - there's one of every color, with green being plentiful, but some are more interesting, like this one - Shadow Council Cowl - Shadow Council Cowl - Item - World of Warcraft
- Face-wraps - Outlander's Facewrap - Outlander's Facewrap - Item - World of Warcraft or the crafted White Bandit Mask - White Bandit Mask - Item - World of Warcraft
- Dalaran wizard hat from vendor
I only did this for cloth helmets, but you can look up every armor type and see what comes up. I expect other popular choices to be knight helms, bezerker/horned helms, floating crowns, helms with crystals, etc.
Robes
Again some loose criteria:
- anything pretty/with an unusual design (i.e. robes that don't look like every other Northrend and Cataclysm piece). Some examples off the top of my head:
- Elegant robes - Elegant Robes - Item - World of Warcraft
- Silver-thread robe - Silver-Thread Robe - Item - World of Warcraft
- Solstice robe - Solstice Robe - Item - World of Warcraft
- Scholarly robe - Scholarly Robes - Item - World of Warcraft
- Sanguine robe - Sanguine Robe - Item - World of Warcraft
- Thistlefur robe - Thistlefur Robe - Item - World of Warcraft
- Lunar Raiment - Lunar Raiment - Item - World of Warcraft
For this category, I'd advise searching primarily Vanilla models. Some of them are really awesome, elaborate, and distinct from anything they've done ever since.
- anything skanky - yep, especially for leather/mail/plate. Seek out all the plate bikinis, strappy tops, etc.
- thematic - some people may want to look like Jaina, Sylvannas, Tyrande, etc., like a Dalaran mage, a Defias bandit, an Exodar vindicator, a blood elf magister, a Stormwind soldier, etc. Tracking down these pieces might take some time and research, but the advantage is that you can sell them as a set (might require barking or advertising on realm forums).
Belts
A lot of us are saddled with ugly, huge wrestling belts. A simple solution would be buying some simple belts in various colors to resell later.
Pants
Since I think a lot of casters will go with a pretty robe, I have a couple of suggestions here:
- kilts in any armor type, for those who want to wear a tunic
- bikinis, 'nuff said. Glorious Legplates are a good example - http://www.wowhead.com/item=14970
- pants with some cool decorations on the sides, perhaps.
I haven't researched these personally, but I have to share a gem with you:
Whitemend Pants - Whitemend Pants - Item - World of Warcraft - crafted BC pants. You can't see it in the Wowhead screenshots, but if you try them on on a female character, I'm pretty sure they are assless. Or maybe they just look assless on my characters. But yah
Boots
Again, not something I researched personally because all boots look the same on hooves (especially under robes), but sandals may be in demand, as well as boots matching robes/pants you may have found. So if you stumble upon a nice robe or a smexy plate bikini, look up the boots with the same prefix.
For anything skanky, bookmark this thread: http://us.battle.net/wow/en/forum/topic/3053956119 This gal/dude did a hell of a lot of research on various sets for all armor types. If you have the patience to go through it, it's a gold-mine.
2. Go through your crafters' spellbooks and see if you have any cool-looking items with affordable mat requirements. It could be something as simple as Imbued Netherweave Robe (Imbued Netherweave Robe - Item - World of Warcraft), Imbued Netherweave Tunic (Imbued Netherweave Tunic - Item - World of Warcraft), Soulcloth Vest (Soulcloth Vest - Item - World of Warcraft), Imperial Plate set, Jungle Sets, Black Mageweave and Cindercloth sets, etc.
Blacksmiths can do the same with weapons and shields.
I know that this guide is nowhere near complete, but hopefully it offers an idea of what to look for and where to look. If you think there might be a big market for transmog gear on your server, I would say start with Wowhead, make a list of prefixes you're interested in, and add them to your snatch list if you have room. You don't need to try reselling them for thousands if they're pretty common, but it's not a bad deal to pick up a few things for 2-5g a piece and resell them later for a couple of hundred or more.
