Contrary to what some people assert, slower battles remove tactics and strategy from the fighting as everything is decided by infantry grinds and units that rely on shock and morale effects are nerfed into oblivion as is any sort of damaging magic. Having only one effective tactic makes for a poor battlefield experience. I've played Rome Total Realism with its snail pace battles, it sucks.
Also, I don't see how "you can't watch your men fight" is a thing unless your reaction time has been crippled by weed abuse or something. I can zoom in in battles just fine and still not lose sight of the bigger picture.
