I definitely approve, I think doing that and adding some ability pruning across the board is a really good idea.

Get rid of invigorate, lower tp costs across the board or just get rid of the TP system altogether, add a sprint bar, leave the combo system and call it a day.

Ditch abilities like fist of flame, heavy thrust, maim, huton, and just fold their damage bonuses in to the base abilities and tune around that, etc.
