There is another train of thought (@
Stede brought it up i believe) that suggests NOT pre-crafting to avoid any possibility of losing stock when 4.4 rolls around (i.e not having 40 glyphs turn into
[Charred Glyph])
I think both ways have pros and cons.
Pre Crafting
Pros
Won't have to afk craft everything on patch day, which allows you to:
Post immediately
Ignore most technical issues (post and log)
Set the price (to an extent)
Cons
May lose a stack or two
SMALL chance you lose it all. I'm not entirely clear on the programming that goes on during a patch, but i'm not completely ruling out blizz assigning all glyphs a
[Charred Glyph] ID and THEN reassigning new glyphs, old glyph IDs. I doubt this will happen...but its been bugging me...
Post-Crafting
Pros
No chance of losing any money
Will have the same or more stock then an equal pre-crafter
Cons
Prices will be set (to an extend, they will still be very volatile and prone to manipulation) upon market (re)entry
Couple hours of CKS to get your stock completely ready
Sales more affected by technical issues
Although the technical issues aren't a big concern. If the server goes down, no ones buying stuff anyway.
However the important thing to note is if you are stockpiling correctly (i.e doing what @
Kathroman says) the difference in profits from these to methods will probably be trivial.
Food for thought
