Remember when Youtube changed its layout and you were one of the people that complained?
Then it happened again, and you complained again?
Besides, this is different because it actually changes the game in an extremely significant way. It takes longer to buy items, it takes longer to find them. LoL is just turning into another DoTa clone, arguable some would say it is already but the walls defining their difference are shrinking ever slimmer.
Point being, LoL was different and unique, this update makes it not unique and not different. No reason to play LoL, why not go play Dota?
