Ranked game with heavy lagg exploited

[KnightFandragon]

So, does this lag exploit explain while in game it goes fine for awhile, no side getting any real upper hand or one side is barely winning. Then at some point in the game there is a huge lag spike then right after it one side starts to just steam roll the other and units cant hit, get 1 shotted, cant kill anything. My dad has had that happen a few times.
