First of all, I dont like pet classes... I simply dont enjoy micro managing my pet.
That said, I've a few 85s but am left in a dilemma which one I should focus as my main:
Warlock
Although I dislike pet classes, in random BG I dont really have to micromanage... I'll go with Warlock if I cant find another class.
Death Knight
I play as Frost and enjoy it.. but seeing as how Unholy is considered the better spec now and for 4.3, I dont want to deal with pet.
Warrior
This is the class I've been playing a lot lately.. but in random BG, most of the time nobody heals.. while I do enjoy playing as warrior, I wonder if there is another class that suits me more.
Mage
Frost mage... no thanks because of the pet. Fire is pretty fun in BG.. but so squishy that sometimes I'm frustrated at how fast I die..
Shaman
Elemental is the only spec I would go for PvP.. but I last tried it in Wrath... how is pvp elemental now?
If all else fails, I would level my Priest. Spriest is something I think I would enjoy... it has no reliance of pets (except shadowfiend) and judging by the patches so far, not really under/overpowered.
I realise I've soo many 85s
