The real problem with Twisted Treeline Ranked

The problem with twisted treeline ranked is this. You get placed in a very low rank like iron 4. This should not be your rank. Lets say win 2 out of 3 games. You start off with 30 LP Iron 4. You win two in a row which usually a win is around 20 LP a game. So you go from 30 LP to 70 LP. Then you loose a game. That brings you down 15 LP. Now you're at 55 LP. You don't advance fast enough. To sum this up you get automatically placed in low iron and then rank up slowly. There is no motive to play. It's such a chore to even leave iron in TT. The reason people even play TT in the first place is because it's a smaller SR. It's more kill based and fast. You could fix rank it's just right now you get put in a lower skill rating then you should be and have to climb out off a hell hole.
