Well it's all coming down to the specifics of the realm...
I have chars in two servers. My first and main char is on a realm that has more than adequate Alchies. Therefore prices are not high and materials are better off some times. This means tha Alchemy has sense only if you farm your own mats. On the other server and at horde side the situation is completely different. Players begging for potions and elixirs. It's a PvP server so you can guess the issue... Anyway eventhough my main there is a warrior I will take alchi as a trade.
And last but not least, with 2.4 transmuting will have lower if none CD... This means prices for arcanite etc will drop dramaticaly...
Anyway professions for money are ALWAYS realm-relative!
