Having the same trouble myself, worst was today when the game froze up twice. It's really annoying. At first I thought it might be something on my end but since it seems like others are having this trouble I'm second guessing that.

bump, SEVERE lag and my friend also got bumped to level one and was unable to use any of his abilites or items LOL wtf.

I've just lost a Ranked because of this. lost the promotion, this really piss me off, Riot u may lose a lot of ur players if u keep up without doing sh*t

Bump

I've just lost a promotion ranked game, this piss me off because there's no way to explain this issue to ur teammates who are trying to climb in ranked, Riot if u dont work on this lagg, You may lose a lot of your followers... Plz just work on it

This game is awful for lag spikes

this lag is getting about out- of- control. Always getting mini lags session, freezing and complete shut down of the game.. riot please look in to this problem, especially around the oceania regions e.g. australia.
