Thanks for the thread link. I've avoided T2 because it had a reputation (well-earned in the past) for being a rules-lawyer-y format. However, T1 has become just as much that, and the fact that only maybe 5-6 decks have any chance of competing in T1 has become a huge turnoff foe me. (And yes, I have one of those deck formats that I've tweaked and played.) As a fairly mediocre open deck player, I have no illusions of becoming a top competitor at high levels, nor do I plan to be. (Not enough time to play, for one reason.) But I'd prefer a format where you can try out several different decks and at least provide competition for the other players, and maybe have a chance to place at some of the lower levels.
It's either that, or sticking to booster (which I started out hating, but which has become my favorite format, not to mention the only one in which I am sometimes competitive).
