When I'm controlling a full party of 4-6, I prefer to have Fighters and other non-spellcasters play more straightforward with less choices. It's a good dynamic with melee and magic. If every single character has a million choices it slows things down. And I don't like exotic combat abilities that look and perform like magic.
Martial classes still have lots of tactical options in D&D even without crazy abilities. Placement, who to engage, shoving away or prone, battlemaster abilities, action surge...
