I would recommend Heroes of Battle... Its "victory point" system enables PC actions to actually matter...
I shall check it out. The problem we had wasn't even the lack of player usefulness in battles, it was a logistical problem of trying to find a way that strike a fair balance between not boiling down the entire fight between two single units on the field rolling one attack each (not very dramatic) and turns not taking 30minutes each of having to roll 30 dice rolls for each side due to multiple units on the field. I like the option to display multiple miniatures to represent different parts of each army, but keep it reasonably simple and fastpaced. Anything more difficult than the base 5e rules (or similar stuff like vehicle combat) isn't want I want.
My party couldn't care less about advanced tactical tabletop combat, they just want to see a lot of minis on the field and feel like army generals.
