I play warlock, and used to play wizard.
I prefer warlocks. When it comes to grinding, both can solo fast, but with wizard you are going to die alot more than with warlock.
About pvp, wizard pvp's are boring, either u 1 hit, or they 1 hit you.
I haven' t done much jobbing so i won' t comment on that part of game.
This is just my opinion, to me warlocks are the most fun to play euro class.
About sp needs, they both cost alot of sp, warlocks need almost all of their skills, same as wizards.
Hope i helped
