Before I get started I'd just like to say that /remake option is one of the best things to happen to league in a long time. However, there are scenarios in which you don't get the option when you should. I'm not talking about trolls/inting players, since that's kind of impossible to track live, but often times people connect at the start, either stay afk in fountain all game, disconnect or just leave the game. This has happened twice to me in the last 2 days (once to my team, once to enemy team).
Maybe there should be something implemented into the game in order to catch these kind of players and nullify the LP loss/gain. Just like when multiple players are experiencing connection problems, the game gives +/- 0 LP to all players. Maybe the game could track level progress of players while in game, and if someone is the same level for X minutes then he's considered AFK or something along those lines.
It just isn't fair for people to lose LP because someone left or dc'ed.
