Yeah for PvP you should go Affliction or maybe SL/SL or something and Destrucion could be tricky with shadowfury (right name?) some kind of 0/21/30 for alts and something like */*/31+* so you can shadow fury + nuke with the rest it's like a Mage Combo main Frost with Imp blizzard and the rest is Nuking and in PvP it's good to have Felhunter against fear and Nova or something^^ and Unstable affliction isn't a problem he heals himself the silence isn't longer than the CD of his Dispell

The speccs are just for PvE and for focusing on imitation of Grp play. And DMG improvement as wel. But heroics tanking with only a Pet? I guess it's a no go, sad but true, I would love to see Warlocks doing such a thing maybe with a Healer would be cool.

In the speccs I left "Improved Channel Spells"in affliction tree empty, because the locks shouldn't get aggro with the Improved VW, I hope so.

Hm with a healer maybe it'S going to be possible, a priest should be able to shield and heal him or something, but I guess you'll get aooner or later aggro Problems in Boss fights. Maybe Felguard could tank. Oh My ... my brain is going crazy again, it's so excited to do something ^^
