Because a person lagged twice, at times that only coincided with game events, specifically while losing, and until the end of both games. If the person had lagged at random intervals, periodically throughout both games, I would have not mentioned this particular example. But, in one of these games, the lag frustrated my partner into leaving the game and the other side began to win (the AI repeatedly fed itself to the enemy team). Coincidently, it was only when the team pulled significantly ahead that the lag went away (in domination mode). But, when they began losing again the lag predictably returned.
Alt tabbing or elevating your ping is incredibly easy. I'll alt tab out of matches, periodically, when there is no chance of death and victory is assured. You seem to be selectively attending to the later section of my first post and not the fact that there should be a general way of removing people with horrible connections from the game. It would be nice if everyone had decent connections, but forcing three other people to suffer through five second ability lag and stuttering play makes the game intolerable. I never stated that my particular anecdote was prevalent, for it may very well be an isolated incident, but because there are no safeguards in place to prevent this behavior it could happen to others. A threshold, set around 500ms, would not be entirely unreasonable. Even 1000ms would be adequate. A more common, and less malicious, lagger I see is someone downloading something in the background and refusing to turn it off while they play. In such instances you can only tough out the horrible gameplay or quit and accept the loss.
