WAR needs to return to its 'mitigation though damage" tanking style. They tried to make WAR a "safer" tank to play, ex removing pacify on berserk but they completely missed the point of WAR. We are supposed to tank "recklessly"! That was the whole lore behind WAR. They need to give war a better self sustain in any stance and not force them to Defiance just to self heal. The OP hit all the marks when it comes to issues with WAR currently prior to 4.05. I'm also curious as to why savage raids still have 2 tanks. If you have one tank main tanking the boss guess what the other tank is doing? They are dealing damage. Unless a fight has adds 100% of the fight duration the other tank will be in dps stance.

But SE didn't include tank damage calculation so in theory the OT only needs to be there for tank swaps and any other time that they are not tanking they can afk because their damage doesn't count towards the overall raid? A bit hyperbolic I know but the point is don't assume that tanks won't help the party with dealing damage when they aren't tanking and don't punish them for doing so. WAR is only trying to help in the only way they can and with the only skills you provided them in 4.0; and that's by acting as a dps.
