Ok back to emus and finally time to repay your efforts you damn exploiters
I've just done this right now, I believe it's the latest ascent rev. A friend told it to me, I confirmed it, I believe it isn't posted yest in this board or if it is this is damn old and I didn't knew about it (been away from emus for some months).
So just choose two professions you want, any will do except blacksmithing. Go to Booty Bay and talk to the blacksmithing trainer there. Even though you have two professions already he will let you learn it.
So now you have three professions. Unlearn Blacksmithing, relog and go learn two new professions that you want (you can find leatherworking, alchemy, herbalism and engineering trainers in booty bay). When you have four professions just learn BS again, unlearn, relog and learn two more till you have all ten professions.
This will not bug you character at all, at least where I've tried it. So enjoy.
