Laggy, yes. My connection to the game was fine and I saw lag, something I do not see unless my connection is utter garbage.
Things I think Riot should consider looking into:
Key "~" something personal but something probably worth considering.
Key "-" Something to most certainly look at.
Riot~ Please lower the awesomely insane quality of this client. Odd request I know but it just way too much. Way too much for me to look at. (Though absorbing the info is fine, it is just a lot to look at)
Riot- Please fix lag on this client. One should never experience lag unless, in-game terms, their ping is about 10,000 or higher (or whatever the old client used to be)
Riot- Please fix Custom Games and adding bots to fight against/with. I can only go alone with would only help my jungle clear but nothing beyond that (build testing, trying champions outside of bot games and Normals)
Riot- Please fix the connecting to the game. Every time thus far (which isn't a lot) I have played a game, I failed to connect. Taking about a minute to get to the game.
Riot~ Please look into spectating a friend's game. For some reason, I cannot spectate a games match.
