I would agree.
I've only been playing for 2 days now and last night I was constantly being put into games with people from lvl 30 up to lvl 90. And the icing on the cake is when a lvl 50 calls me out saying how much I suck. Well, no ****? I'm lvl 10 with half a dozen of in game hours, if that.

I'm just getting to grips with the map layouts, still not sure where enemies will come from or what strategies they will use.
On my first night however, It was putting me in games with people around my lvl, at most a lvl 20! I wonder if it has anything to do with the time of day? I noticed in the past playing LoL that late at night, you were being pared with much more competent players vs when quing at peak hours.
