I like Champ Select and Dynamic Queue, but Here is something to chew on.
However, I'm g etting less experience with my 3 weakest roles. I don't really play top, mid and support anymore. I'm probably suckier at those roles now than I was when I was occassionally forced to do so by popular demand in the pregame lobby. I am now better at 2 roles and shittier at the other 3. I think there was some suspense every pregame lobby because league was like a box of chocolates. You never knew what you were gonna get.
Also, I've heard the idea thrown around that 4+1's should be removed, and I agree. It should be 3's and 2's, 3's and 2 solos, but never 4 and 1 solo.
