Personally I'd just knuckle down and level up your existing BS. 86 to 90 really isn't that awful and you won't need to do much int he way of rep-grinding, since you only really need Klaxxi, which you can get to revered just by levelling from 89 to 90 in Dread Wastes (with a grand commendation).
Unless you really hate melee classes, ret isn't too painful to level, particularly if you can find a decent BoA weapon like
Engineering is just too useful and too painful to level for me to feel comfortable with dropping it.
