I'm really glad what Blizzard did for the season 3 ranks. I thought I've never going to be able to climb to diamond after just constantly getting pulled down to gold from platinum for whatever reason.
I think mostly just because of waves after waves of new players starting from the gold-platinum rank. Knowing nothing of the maps, mechanics and synergies and thus getting frustrated and throwing games, trolling with shitty picks and refusing to communicate.
I'm glad I've finally gotten over those and getting some really awesome matches when everyone is pulling their own weight.
