well tbh i think you're wrong in your statement that the overwhelming majority of combat talents does nothing, every tier of talents have a talent that straight up gives you an extra button to push, thats slightly over 1/3 of the "combat" talents that gives you something extra to push/do, to be exact 48% of all the talents gives you an extra button to push, i wouldnt say thats an overwhelming majority, i will agree tho that most of them gives a passive effect but that just adds depth to the spec.
