So, you get better at not being allowed to use flash? Unless Riot implements summoner ability bans in ranked, I don't see how this is good practice. Some champions almost NEED flash to utilize their kit optimally (thinking Skarner, Alistar, Sona to an extent, Fiddlesticks, Amumu). That's like practicing with a 15 lb baseball bat. It's not going to make you a better batter, its just going to make your timing worse when you get back to actual game situations (they've actually shown that warming up with extra weight in timing sports just throws off your timing and doesn't increases power).
