ThufirYeah, talking to people in the middle of a huge event is not the same as giving them time to think and then vote. Especially when not all the people who should get a vote were there - the captains of the other six Invite teams should get to vote as well, and I doubt Killing took the time in the middle of LAN to talk to all of them.
Point is, regardless of the circumstances surrounding it, the question of whether to ban the Quick Fix should be treated the same as the question of whether to ban any other weapon in the game.
I highly doubt the other invite teams even came close to getting the same amount of practice with the quickfix. Most of the lan teams only picked up quickfix because mix^ was running it and it was too strong to not run it when playing them. Almost everyone there wanted it banned after having to use it for 3 weeks.
