NIN will still most likely be OP and they still have their utilities. If DRG can now do as much damage as MNK, this will now make MNK the weakest DPS jobs since MNK will still be hindered by their positional and they do not have any utility to benefit another job like how DRG benefit BRD. I guess they still have the Dragon Kick INT debuff, which can help in 1 or 2 fights I suppose, not nearly as good but its sometihng. But I guess we'll see.
