Ranked...

So I was put in silver III last year, and as I read the new system it said I would be placed lower, etc and this season I was put in bronze 4. While that is no problem for me, as I can work my way back up, I have a problem with the people. The past 4 games, I kid you not, 4 games in a row, one or more(two in one game) of my teammates have left the game leaving it 4v5. It is extremely demoralizing because we are already under pressure to win so we can get ranked up, then when it's 4v5 it's just like a slap in the face. There really needs to be something done about people leaving ranked games. It's completely unfair to whichever team is a player down. Change it to be like DOTA or something where you can all leave the game and it won't count, or you can recruit someone into the game. But me losing 25LP per game because my teammates leave is not fair in the slightest and it getting rather tiresome.
