I'm just here for this bug:
I usually dont use my stats points every times I lvl up, and I realised that once you get to lvl 38 and 39 traits points seems to decrease.
lvl -> traits points
35->3
36->3
37->2
38->2
39->0
I realised this by lvl up my tank at the end of the game, using all of my wisdom crystal(s?).
Edit, I just realised that there was an update,
this is for A3 RW v1.0 windows.
