LOL Looks nice on paper but that's all it is. I'll take my real life experiences over some nifty math anyday. However lets look at some things you ignored that will change those damage totals a bit. Give the other fighter brutal, something the minotaur here can't use.
Now lets attach a race to that other unnamed fighter. Lets make him a dwarf. Now the dwarf takes Dwarven Weapon Training and the minotaur takes weapon focus so same damage bonus at paragon. All other feats ans stats the same. The minotaur has a maul while the dwarf has a Mordenkrad. Lets go back and see how many of those 160 rolls the dwarf made where 1's. It'd be average that's 26 rerolls. How do you think the damage stacks up now?
Now look at the same two fighter, but with weapon and shields. The minotaur ends up with a d12 broadsword and the dwarf has a d10 craghammer. Make those damage rolls once and see how it comes out with all 1's and 2's rerolled. I'm betting it's not a big difference.
The only time the minotaur comes out ahead is in crits and that's only 5% until we're in epic and we really don't need to worry about that ANYTIME soon. I think we don't need to worry about super optimized epic minotaurs anytime soon.
