PLD - Cover
Reason: Because if someone else has aggro over mobs, then you're not doing your job correctly (barring A2S snipers). Also only blocks physical.
Fix: Possibly shorten CD? Maybe even allow cover on 6 second oGCD like cleric stance? That would be interesting.
DRK - Unleash
Reason: Not saying skill is useless, I just find the least reason to use it. Only ever use it to grab snap aggro, then Blood Price + Abyssal Drain or Dark Passenger.
Fix: Doesn't need a fix, I just don't use it as much since it's on GCD and only used for snap aggro when I run 4 man dungeons (which is not often).
WAR - Steel Cyclone
Reason: In situations where I do need AOE Enmity and DPS, better to snap aggro with overpower, then build stacks and use triple Decimate. This method is much stronger than using all Wrath stacks on Steel Cyclone since WAR has no AOE enmity issues.
Fix: Possibly reduce stack consumption from all 5 to 3? I feel like this skill does not have a place when Overpower and Decimate exist.
