In my opinion tanks need 2 things right now:

1º more dps: it's unrreasonable have healers breathing at our necks when we are supose to be much more agresive than them and our contribution to the raid it's frankly low.

2º more complexity: the role feels empty and to simple to be considering fun, heck even the JP forum are disscussing about this too, the quality of the role has been decreased despite of the necesary changes on the role, we need more skill ceiling and more mechanics to be worry about in all encounters, using simple rotations and use a defensive or 2 to survive it's feel lame at best, we should have stuff that reward you for proper use and optimization of our jobs and feel impactful to the party.

it's hard to belive since i was one that wanted the tank stances changes and the acc ones too but all the changes around it making agro meaning less, defensive skills optimization a joke and our impact to the party insuficient make me wanna go back to stormblood without any doubt, this amount of oversimplification has been gone too far.

just my 2 cent.
