Let it be known not a word was mentioned about lag. The replay shows he killed fallen_soldier's peon, he passed right by 00logan's peon letting it live, then he killed mine. This is not indicative of wanting to eliminate lag.
When this is allowed on the server over and over it becomes kill or be killed for watchers. This means they have to build and can't watch what's actually happening in the game. Also, war2obs doesn't work if you're building. If the watchers get in the way of the players they will get upset. Eventually, booting increases. It also ruins any form of streaming and recording to promote the game.
