Looking at champions' abilities and features I'm not sure all 10 people on the map are actually playing the same game. Quite the opposite in fact.
What do I mean? Well, 50-70% of champions (below 4000BE) have QWER and leveling up due course of the game those get stronger and/or on shorter CD.
Now take Kayn/Rengar/.. basically any 4800+ champ and compare. 1000 dashes, 10000 teleports, invisibility, self heal, terrain traversal, choice what to select, what to collect, ...aaaaaaand those getting changed/modified with leveling up!!
Really, Tencent? I have nothing against getting more interesting and complicated gameplay mechanics, but this is a teamfight-centric game and 10 people SHOULD play with more or less same ability set.
Truth be told LoL is just a game where new people vs smurf accounts opened is showing a dead end.
