The problem I have with your perspective is there are a couple of different scenarios that make the cool down period kind of a slap in the face. First off if you are actively looking for a club, you find one and play a game and realize these guys are a bunch of dick cheese burgers. So you leave, you find another club that's trying people out but oh wait, you have 2 hours and 41 minutes left before you can join a club.
Also other people have mentioned that not everyone enjoys the multiple dressing rooms for a competitive advantage, some people enjoy it because they don't have to tell people they can't play because the other line is playing right now.
I honestly never viewed club hopping as a big deal, people like to play EASHL rather than deal with the ****sticks that play OTP. I don't understand a system like this at all from EA's point of view, were club hoppers that big a problem that you introduce a system that's going to encourage people not to play your game. If you play for a competitive EASHL club, and you can stomach 3 hours of OTP I give you serious props.
