I just leveled my alchemists up to the transmute: liviing elements or whatever recipe it is. pulls in pretty decent profit, considering I have like 18 alchemists and once or so a day I fly them over to uldum and make a ton of air; i'd highly recomend it. Granted, I was at 450 from the epic gem craze in wrath, but still,taking 18 chars from 450 to the first xmute paid for itself in like 2 days.
