I agree with most of the post.
But i dont think that glass cannon is too strong. ( a bit weak for melees and maybe a bit too strong for archers ).
Rage should be self cast only and maybe add some real drawbacks ( get 50% more damage maybe? )
Warlord is a bit strong yes but should be okay with 1 AP / kill ( or maybe cap it at +2/round ). I think and hope that enemies in Tactitian and/or later in the game will survive a bit longer -> Warlord becomes a bit weaker.
For Attributes i agree we should not be forced to spend all our points just to keep up. Maybe just 1? Or just remove this and only allow us to spend 1 Point/level.
I also think that mages need some kind of buff. The memory system + high cooldown is really bad for them. Maybe decrease the spell cooldown by increasing the skill ( Hydro 3 -> -1 round CD for example ) or at least 1 spell on a wand ( water spell on a water wand etc. ) and atleast 3 skills on Staff. I dont see the point to choose a Staff above 2 Wands right now.
