This won't be fixed with this mod.
It is more of a ... bad network code problem.
Possibly patching the client.exe somehow could solve this, but, that's something that is way above my head.
Also, any UI thing that opens will cause FPS loss.
Oh, btw, if you do 6v6, DO NOT USE THAT MOD!
It removes all pings from the map (they are particles).
And keep an eye on the daily challenge quests, as you won't have the annoying effect saying you have completed them.
