Having a high ping in unlagged still puts you off on a couple disadvantages. Your shots/attacks still connect late so low pingers can beat you to the punch, but also, because movement is not affected at all by unlagged, aliens can be difficult to play sometimes because pouncing and other such movements still feel rather slow with a high ping, as it always would with unlagged or not and a high ping. You still get the fair chance to hit something when you get to that point, but mobility is something aliens rely on heavily, obviously, and a high ping will always hinder it, unlagged or not.
