Considering that in the last few editions every melee class was reduced to:
Basic attack every round, while all the casters did the fun stuff...
Not arguing with you, just wanted to say that I've heard other folks say this about 3e, too, and I never get bored playing my 3.5 fighter.
I rarely basic attack. I usually Power attack 2, but depending on the target's AC, I'll PA 5 or 10. If the target has a high AC, and is 2-legged, I'll sometimes use Improved Trip with my heavy flail to effectively lower the target's AC by 4, (and let anyone standing nearby take a shot at it as it stands). If we're fighting many foes in a large area, I'll activate my Boots of Speed, so I can get where I need to be most, (otherwise I can only move 20'). If a foes has half as brain, and is focusing on another (less melee-focused) party member, I'll use Goad to attempt to turn the focus back to me.
As for positioning--depending on the terrain, I'll try to put my left side against a wall or a barrier. I prefer narrow gaps that I can fill to slow movement past me, when I can get it, but caltrops are a good way to slow movement in slightly wider openings. I try to sidle up to a couple enemies, so Cleave will kick in, (but not so I'd get flanked). And then there's weapon choice: stick with my bludgeon, or do I have to use a slashing weapon instead? I have other tricks up my sleeve, and there are dozens of other variables, but you get the idea.
So while the others are striking from a distance, casting spells, dealing with traps, healing or whatever their thing is, I'm dealing with dozens of battle field variables, pitting my tactical knowledge against our opponents, and having the time of my life.
Again--not arguing that you should see it my way. Just sayin'.
