For most fights - not all - today in FFXIV, tanks do not deal with anything unique except for the occasional - if not completely absent- "Tank Busters", leaving them with most of their Mitigation tools on " optional or Emergency use" only.
What if Tanks have to deal more with during the fights which force them to rotate through their Mitigation abilities?
My suggestion is the following:
to let the enemies enter a state of "Rage" periodically during fights, this state lasts for 10-15 seconds and can either (increase Autoattack damage by 50%) or (grants a 50% chance that Auto attacks will crit)
This applies to bosses only, or all enemies if you want to go to the extreme.
Let me know what you think?
