Alchemy

Alchemy is a very important part of high end PvP and raid content. Almost everyone has the pots that they want for any important confrontation with either a raid boss or a world PvP target. You can either be a supplier with lvl 375 alchemy, a beggar who dumps tons of gold on the Auction House to get their daily fix, or a guild leach who is always getting discount pots from the guild alchemist. If you're here, you've probably already decided to choose the former. So, in light of such independence, it is easier than it may seem to level alchemy to 375.
