Yep. I started WoW as a warlock around patch 2.3. He's now 80 and has been for some time. I've had ample opportunity to experience endgame PvP and PvE and I have loved him. But i think i've hung up the cloak and demons in my WoW closet for now.

Felguard builds are fun, but useless in a world of weak pets in PvP and massive AoE in PvE. (Amen, patch 3.2 Fel Domination changes!! :D )

Destro has always had a fun feel, and i like it, except after using it as a main spec for several months, i can firmly agree that it plays like a broken, third-rate mage. (Hello! Fire Mage already exists. Is there any other class that has an identical spec to some other class? i'm not sure, but i don't think so. I personally feel that having one warlock spec be a copy of a mage spec is just... wrong somehow.)

Affliction: it's a spec about DoTs. If you take away some DoTs, making it easier and faster to dispell my attacks in PvP (less debuffs to remove), then please... PLEASE make them hit harder. really hard. Like give me something like shadow priests where my target has their movement speed automatically slowed (apply CoEx) when a target with Corr, CoA, and UA is being drained by me.

And frankly, all warlock specs suffer with mages in the AoE damage > casting times war of Ulduar and even Naxx PvE. Movement fights and raid-wide damage makes casting DPS suck it's own sad, scrawny rear end.

Have an 80 druid and DK. They are getting all my play time lately and for the foreseeable future. The little warlock inside me dies a little more every day. Bring him back, Blizz.
