Opinions: Should tanks work for aggro?

[Absurdity]

What irks me is that they really didn't.

What they did do is remove / reduce the number of buffs that actually go out.

Except then there would still be about the same difference in dps contribution between tanks and dps as there was in SB and HW, because everyone lost those buffs.

The difference between a warrior in HW and a BLM was about 25-33%
The difference between a warrior in SB and a BLM was about 30-35%
The difference between a warrior in ShB and a BLM is closer to 40-45%

This assumes both are of equal level in skill

Our level 1 trait "Tank Mastery" says "grants a bonus to damage dealt based on your strength attribute"...what it actually does though is literally reduce our attack power modifier.
Are they "intentionally trying to keep tanks down?" Who knows, but there is a noticeable decline in tank's overall dps contribution. Combine that with the added decline in responsibility or actual influence on a fight that tanks have and you see an issue.
