[Lonestar]

Reaver more than often tends to be shafted by Flottement users when you proc Evasion, by stepping either backward, sides or even diagonally. Not to mention the same as the above, but the class's skills was buffed because it didn't provide enough damage for its FP cost, so I'd rather not bring this ping-pong of buff/nerf. The main offender of this is either the fan tomes, or Martial Lawbreaker itself. (Could always limit it to sword/spear/axes.)

I do agree with Winged Serpent having a bigger cooldown, but not with Snake Dancer's. Blind, knockdown and rear attacks already seal the deal with that trait, and things like DoTs like poison tends to remove one stack at the beginning of the fight. That'll leave them with one 'invicibility' only and be vulnerable for the rest of the round, which, mind you, Snake Dancer's users tend to be really squishy.
