I don't care how special or powerful the moves are. No QTE's in a turn-based combat system.
I don't mind an elemental booster skill, or a trail of fire skill, but separate them into two skills so I don't create a fire barrier between my allies and the enemy when I just want to boost my power.
This game is not Minecraft, so I'm quite sure that letting players modify terrain to divert rivers would indeed require far too many resources to implement. I'm sure you know that they didn't have the resources to do a traits and talents thing until the KS, and that seems far less complicated.
