The issue is that WAR DPS is through the roof (as is DRK, and PLD is too high).
If you'd like the statistics for Thordan, here is the link

In this case, WAR performs better than in A1S, where they are ahead of both BRD and MCH and put out 85% of the top DPS job (MNK at 981) at the 75 percentile.
If you're curious as to how I think it should be balanced, this
roughly how I'd like to see damage numbers. (numbers are to give a general scope and not actual balanced numbers)
Single target
MNK 100%
NIN 98%
DRG 96%
BLM 95%
SMN 90%
BRD 80% (depending on song use, without song use numbers would be higher)
MCH 80% (depending on turret use, without support use numbers would be higher)
WAR 45%
DRK 40%
PLD 35%
SCH 15%
WHM/AST 10%
AoE
SMN 100%
BLM 95%
MNK 80%
BRD 90%
MCH 90%
DRG 75%
NIN 70%
WAR 20%
DRK 15%
PLD 10%
SCH 20%
WHM 15%
AST 10%
give or take, but that general spectrum. In other words, a WAR should be pulling less than half of the top DPS, not 70-85%.
