Requesting a game type "race wars".
For each race a team should be available and each team is a different race.
Maybe a extra feature like adding races and removing races. To support 1vs1 teams or 1vs1vs1 teams.
You mean for example in a BA 4v4 teamgame one team would have to be completely Core and one completely Arm if "race war" mode is active? I have been wanting this myself too, i quite like this idea.
just add ingame allying / unallying.
everybody starts as enemys, then if you find a player of your race you ally with him. Thats how it works in starcraft.
