Just turn their name red, make them worth xp to former friendly units, and unable to be healed. Make it really suck for persistent abusers.
DjemoSRB, I agree with you, but to clarify, I think the animation would be for the pleasure of others not the traitor. To your point, who wants to see their avatar get owned by an ally, whether NPC or player I think they should add the ability for finishing them off in a special, such as finishing move, way.
Yes the execution of allies by players was mentioned before. And yes it will be a pleasure to get owned by a Grey Knight as those units will not be ingame and we have enough GK fans on this forum. Heck id be surprised if that didnt increase the TKs even more simply cause those said fans would like to see that GK model over and over giddy with excitement at waiting for him to come and slay them so they could fangasm. So yeah, best to keep it at players humiliating players.
Think they played with something around 2-4 secs if memory serves well, but ofc as Galen said there will be weapons that have already been confirmed to be instakill, so yeah, low TTK.
It was around 2 second, that's more than double (3 times maybe?) than PS2 and 5 times more than COD or BF.
Those are all big aoe style weapons. And there will be a place and time where those will be absolutely appropriate. But I am squarely in the camp where every weapon shouldnt be on the table in every situation.
