SoI being the default tanking seal WAS IN NO WAY OBVIOUS.
I'm not quite clear why this point keeps being brought up. This is using old ways of thinking to solve new problems. There is no longer a "default tanking seal", especially once they eliminated the SOT glyph. That should have been evidence to the obvious. Like the Blue said, if you want to do damage, use a damage seal; if you want to heal, use SOI. Thank goodness we have a choice now, right?
Frankly, the only time I see the nerf to SOT being an issue is if a raid is dying to enrage timers and you need to eke out some more DPS. As we have yet to even worry about that type of thing, let's put away the pitchforks and try and embrace new ways of thinking.
All the theorycraft, all the simulations were done with SoT in mind as the default seal, and it showed we were merely adequate. We are not the best when it comes to AoE vis a vis other tanks.
HotR is so weak, I'd do more damage by sneezing on the screen. Warrior's TC has the added benefit of spreading Deep Wounds to all targets rolled into their Weakened Blows debuff -- and we just lost our bleed analogue because we're being pushed to SoI, which means we're losing about 24% of our total damage from Censure/SoT -- which is what helped stick all the mobs to us, and that was barely.
Also, in spite of HW's buff, its effectiveness/priority in the rotation is conversely proportional to the number of mobs you're facing, thus negating its value -- again, this is where our censure was making up for it in our AOE Department.
Ok, our survivability went up, but we're taking a step back in our AoE, and the step back is huge.
