Min-Maxing (lvl1 25AC Fighter) - How to deal with OP Chars as a DM?

[draken50]

I don't get as bothered by more OP passive stuff like defenses. So I'd give the player plenty of opportunity's to be the super tanky distraction. I would also make sure that his heavy armor and whatnot could at times be a liability.

I would avoid having single big monster type fights, but having played a tank it's fun occupying 1 dire mountain lion while the rest of the party dealt with another, and then really turned it into pile of bone and viscera.

Also if the dude is big and heavily defended I'd make him a target of the enemies that were more prideful of their own size and strength and have other minions trying to stay away from him while taking down his help, only going after him after everyone else has run or fallen.
