I use Satellite and have ping of 600-1100ms, and almost never get complaints of warping. So it's a little bit of an exaggeration saying that any connection that is normally bad should equal a boot from the game. A lot of times when someone sees me warp terribly it ends up being them, as I try not to play if my ping averages over 1300. Anything under 1200 and people will mention maybe small warps, but nothing to the extent of being un-killable.
If I am warping that bad, I attempt to fix it, like today I can't play due to the ping going from 2300-3500ms.
