Lag is an issue, and players suffer from it a lot and get unfair deaths. The solution is to get better servers, but OOO doesn't seem to have the money or resources to do so.
For now, I have this suggestion:
When a player lags to the point ofrubberbanding or freezing, that player would be invincible from damage for the duration of the lag.
My game doesn't lag at all. While I'm playing, anything else I do lags though.
