Character skill tree is extremely underwhelming

I enjoyed the game so far, but the first thing I noticed is how small the skill tree looked like. Maybe I have been spoiled by Warhammer, but the character customization looks extremely limited. Aside from a few historical legendary characters, generals in Three Kingdoms are really boring in combat and they barely have any active skills to use.

IMO, they should increase character max level cap, rework and expand the skill tree to include different branches that allow more character customization. So you would have something like a skill tree branch that focus on personal combat, another branch that boost army and retinue with sub branch for each type of combat troop (archer, cavalry, infantry etc.) and a branch for government and administration.
