One thing I've noticed about ladder since GvG release: it is harder to rank up. All the pro streamers, Amaz, Savjz, Xixo, Forsen, Kolento, etc., are having a harder time getting to legend. The number of games they have to play to get there has increased a ton (Xixo didn't sleep till he hit legend and it took him more than 24 hours, whereas 12-13 hours to legend isn't unheard of). From watching their games it seems like a lot of the win/loss is RNG. Watching Xixo play Zoo with Imp-Losion for instance, he won almost every game where it killed a minion and lost almost every game he didn't. He rarely went for the 4 damage if there was another option, but every game he got it he won. Ditto the 3. But in games where he needed it to hit for 3 or 4 and it didn't, he usually lost. I've been noticing the same trend for Shredders. That dev who said more randomness would increase the skill cap was pretty far off imo, it seems to have handicapped the most skilled players.
