Why does it take so long to reconnect?

Alright so i don't know if anyone else is having this problem, but my league client has been acting funny. I have a pretty decent powered gaming PC and i run league at about ~150 FPS so it being on my part is out of the question. Anyway, there are sometimes that my game will completely refuse to load after champion select forcing me to close the entire client and try to load back in before the game starts. The problem here is that the game does not allow me to load in before 3 minutes, i'm sitting there staring at champion portraits until finally my own pops up, only to be stuck at 0% for a good couple of minutes. After that it'll jump to 100% almost instantly, right at the 3 minute mark. This wouldn't be a problem_ IF THE REMAKE SYSTEM DIDN'T FORCE ME TO TAKE THE LOSS AND HAVE A FULL HOUR OF LOW PRIORITY QUEUE._ Which is another thing, it seems completely unreasonable to me to give leaverbuster to people that don't connect when a remake is made, more then half the time it's not even their fault. Leave the leaver buster for the people that actually afk in the middle of the game because of their toxicity.
