Nothing is going to give you the perfect DPS gauge unless we had some sort of "training dummy" to see numbers unaffected by anything else.
Basically what I'm seeing is that
MNK/DRG/BLM are tier 1
BRD/WAR are tier 2
PLD/WHM are tier 3

If they do change how throwing weapon TP gain works do you think it will affect BRD or WAR/PLD more?
