From lore perspective it is kinda stupid that some poopy pants peasant with wooden stick can block every strike from Blood dragons great axe.

And a lot of the time as high lvl melee fighter you struggle to kill even basic trash. You will kill them eventually but very very slowly. Even 2H maces have pretty low chance of breaking block.
Meanwhile rangers and mages can decimate entire armies in few minutes. And they are not that weaker in melee, mages can become even stronger with magic buffs.

And i think that melee careers should have:
1) Talents that give higher chance to break enemy block with any weapon
2) Talents that increase cleave of any weapon

That talents will help to keep up with mages and rangers in killing power and be actully better in melee. And it will be more lore friendly.
