Why the conflicting philosophy?

I'm going to ignore all of the paladin vs. warrior bickering and the "Lol Blizz balances around representation" snickering.

I honestly think it's hard to argue that your choice of tank often costs you a kill because of the dps of the tank. Often those numbers are rounding errors compared to the damage capable by the dps specs in the raid. However, I don't think you even need to invoke that argument. I think it just feels crappy when your dps is lower than other tanks.

I don't think the block diminishing returns exacerbates this much to be honest, but it was a problem that was already there. We'd like to buff Prot sustained dps in a way that isn't risky for PvP.

(Standard: "no promises" implied.)

I'll say again that we have nothing against threat modifiers. Some of you need to stop treating them as if they are cockroaches to be stomped out whenever they appear. Bonus threat is really the only way to keep tank damage lower than dps damage but threat higher than dps threat. It only becomes a concern when A) the threat modifiers are flat (because then when the dps do more damage with gear, you aren't doing more threat with gear) or B) you're spamming abilities that do lots of threat but no real damage, because that just feels lame (and really we're just talking Sunder Armor here, which nobody spams anymore anyways).

Q u o t e:
It does raise a point though, who should GC listen to when a class can't figure out who does what?

It's not necessary, realistic or probably possible for the community to come to a consensus on a change. That's why we always advocate just giving the feedback. It's one thing if other players are responding that the issue you're worried about is a non-issue or that your proposed solutions won't work. I would definitely listen to them and see if they make sense. However, that's not the same as having to get everyone to rally around your idea before we pay attention to it.

It only takes one good person to make a really good point, and it's possible for a lot of people to get excited about a solution that we don't like.

Q u o t e:
The answer has been posted in numerous threads now.

If you truly want to buff prot PvE dps, use the excess rage that exists when prot is MT for a fight. It'd neuter the PvP prospects while increasing the PvE prospects.

Case in point. If it's a completely obvious answer to you and we haven't done it, there is likely a reason. Rarely is that reason because the solution never occurred to us before.

In this particular example, we don't like that solution because it makes you even more dependent on taking damage. On any fight with a tank transition, you might not be taking much damage when you aren't the target.

Q u o t e:
I was hopeful at the beginning of the expansion. Now I am realistic.

Let's keep some perspective, please. Your damage is much higher proportionately than it was in BC, and we buffed Devastate as recently as 3.2. If you want to say your damage is still too low, I'm all ears. If you're saying that the issues constantly come up and we continually ignore them, well, that I'm going to ignore. :)
