Objective comparison of Mnk and Nin difficulty to play ?

[PROBOUND]

Ninja Nerf results are IN! All in all, pretty minor. Say goodbye to 2k Raitons. AOE Katon's will also probably suffer somewhat. Otherwise this seems to be at most a 2% DPS loss.

It is Yoshi P's reply to a post on the Japanese forum.
In short
Aeolian Edge: 50TP -> 60 TP
Shadow Fang: 60 TP -> 70 TP
Kiss of the Wasp: increase damage -> increase physical damage
Kiss of the Viper: increase damage -> increase physical damage

[Edit] There seems to be a mixup with Aeolian and Shadow people saying they should be swapped out (Aeolian 70)
