I don't see a problem with luke banning infinites.
If people can't accept his decisions well too bad, he's the tournament organiser. He puts in a **** load of work and has the right to have whatever rules he wants. At the end of the day infinites are hardly the foundation of anyones game, with the exeption of ice climbers and d3, so who cares if he's just removing a stupid aspect of the game?
If I was presented with two games that were identical save for the fact that in one some characters can infinite, I would choose the game without the infinites. They are dumb, regardless of how cool it is to 'mindgame' somebody into being near a wall. D3 for one doesn't need to mindgame at all if there is a wall, since he can just chaingrab people over to it anyway.
My point is, the fact that luke wants to ban infinites past 5 repetitions shouldn't be something that everyone gets horrified about. He's just taking something STUPID and stopping people from getting an entire stock from it.
He's stopping people doing it for ONE DAY.
I'm sure you'll be able to survive.
