The only new wizard subclass I actually like here so far is Transmuter. Enchanter makes no sense (why would you gain movement and disengage?). Conjurer is underpowered (one time a day features better be AMAZING, and if not they're mostly a waste of space). Necromancy is "ok". It doesn't do...

Greg Bilsland just returned to WOTC as Executive Producer of Dungeons & Dragons. He used to run a Dark Sun campaign.
