There's not much unique-ness when it comes to tank jobs, are there?

You lot cry about wanting jobs to feel unique, but what happens when one of them plays differently from the others? Complaints, whining that x isn't like y.

So you play WAR for...
The unique way Overpower forces you to have a target and only hits mobs in front of you?
Or the unique way WAR does its single-target rotation during an AoE pull?
Wait, I bet it's the unique way Onslaught is a DPS loss most of the time and almost never available when it would be useful?

No, you don't, you play WAR because of the actually unique abilities and features it has; like Thrill of Battle, Inner Release (crits!), Infuriate (bigger crits!), etc.
