Yep, it would be a very good thing to prevent real spawnkill, but I don't know if it is possible.
I just wrote this to try to clarify the spawnkilling term.
Sometimes in sniper role it is very tricky to assault, because you have to defend your flanks, clear flag, then cover teamates... And just one bullet at the time ))
In this case, advance right to flag is just suicide.
And anyway, a camping sniper is a bad sniper, because quiclky everyone know where you are and you won't last long...
I try to play the better here, be fair, balance team when needed, etc. So don't want to appear as "easy frag" player.
Cheers
