People who believe Ghostcrawler (or the other developers) is "out to get" any class are wrong; the developers definitely get it wrong from time to time, but it's obviously not malice.
Except the warlock class. We were handed excellent tools to do damage, seemingly limitless resources, new abilities for pets but my problem is we got things that made us quite similar to a Mage. Was there need for warlocks to get an Evocate to recharge Soul Shards, instant Soul Fire, dot Focus Magic (Aka Dark Intent), an Arcane Power in the form of Demon Soul every 2 minutes, an Ice Lance (Fel flame) and let's not forget even Arcane Brilliance on our Felhunter (in the form of Fel Intelligence)?
My class at the moment with these Mage-like abilities feels too powerful, hence the nerfs. But in PvP the real only way for a warlock to escape is the dreaded, premeditated Warlock Demonic Portal every 30-45 seconds depending on glyphs. Last thing, almost forgot they broke fear to only fear 1 target, break on less damage for 85 balancing issues and so many counters. Well the good thing is I can at least use Fear (the spell should be called Panic because a warlock who uses this is trying to avoid the damage) to not damage the healers and use "Drain Mana" to kill their horrible mana regeneration at 85. It's definitely not a good CC against Warriors, Feral Druids with berserker, Undead race for 10 seconds, even the new glyph of Fear Ward for priests.
Well for any locks reading this, I plan to use Fear and Mana Drain (does no damage so great way to use it) healers in BGs so they're miserable until they nerf Fear again when it wasn't the issue to begin with.
