Remake/Leave system

So i just played a game and i had 2 players who didn't connect to the game (i don't know for what reason) and the 3rd one left at 45 seconds (still don't know the reason). And this is not the first time something like this happens, so when are we going to have a proper and functional leave/remake system? That was a complete and total waste of time, the enemy team wasn't even trying to win, not to mention it takes double-triple the time it used to take to load a game after last patch.
