With MoP coming and that it will have more focus on PvP (the exact same thing was said about Cataclysm), I decided to return to it and did some BGs... And I remembered why I left PvP in WoW.
I play affli and I can duel with some ranged classes, but as long as a melee gets in range I am already dead. Here's some examples.
Last time I did BGs was in WotLK, back then I could try and kite a warrior staying out of his melee range and at the same time, not going far away to allow him to charge at me. But now they have heroic leap, and after that they simply snare/stun/interrupt me. And before these debuffs wear off, I am dead.
DKs don't charge yes, but they pull me closer to them instead, and this can and often is worse, because he pulls me right into a pack of enemy players. Apart from that DKs have ranged snare and AoE incapacitation. The latter has been slightly nerfed, but that didn't help much. But wait, here comes the main dish - the anti-magic shell. It wouldn't be that bad if it just soaked some magical damage, but it also prevents debuffs to be cast on DK. And all of my main damaging spells, DoTs, are considered as such. So this makes a DK virtually immune to my spells.
With a rogue I can't even see him coming before it's too late. He simply stunlocks me and there's absolutely nothing I can do.
Warlock badly needs control/damage reduction spells, so many of which frost mages have, I wonder if they would share some of those... Self healing, for which warlocks have been famous in the old days, is almost non-existent now.
So, PvP warlocks, if you still didn't go extinct, can you give some tips on how to deal with melee classes? And maybe PvP in general.
