Well, time to make a list:

EVERYTHING WRONG WITH WAR

- Tank Stance is weak compared to other tanks, mainly due to SC in giant mob pulls not healing comparable damage to DRK's DA+AD sustain.
- FIX UNCHAINED.
- WAR cannot Shake It Off as easy as the other tanks do when it comes to new skill bloat. Change Shake It Off to something useful already instead of having it be a self-Esuna that isn't used for 90% of fights.
- IR+Zerk Window is difficult as hell to set up in some raid situations, and from what I've seen from others' posts I think that there's some good ideas there to fix this since WAR needs some much-needed utility or something to boost its Damage. One idea to make it work is to have IR free up the Beast Gauge costs for Fell Cleave for 12s. The CD could be increased for this, but 120s I feel is already enough. This would allow WAR to FC 6 times and get the same damage while also allowing WAR to move more freely than it is now since the current build-up is heavily susceptible to mechanics in raid compared to the other tanks' DPS rotations.
- RAID UTILITY OR DAMAGE. It's supposed to be considered the premiere 'Damage Tank' but if it's barely doing above what PLD can do(which is around 50-100 on an estimate) then its niche is not working.
