What if Batman Played D&D?

Just to prove that I still have a sense of humor, here's something I found on a message board:

Yeah, Bats would be a powergamer from hell. He'd carefully research every item, spell, class ability and monster in the game, min/max the hell out of his character, plan for every possible contingency and come up with unconventional uses for everything to let him take advantage of the weakness of whatever they come up against.

DM: You see three large trolls approaching--
BATMAN: I step behind the tree, giving me 75% cover. I use my Improved Tactics class ability to take a partial action before combat begins, which I will spend preparing a flaming arrow to nullify their regeneration--
DM: Wait! Your character has never seen a troll before! How do you know they're vulnerable to fire?
BATMAN: ...
BATMAN: I'm Batman.
