what about the stalker having some kind of highly damaging rear attack, possibly some immobalizing attack? ( stranglehold ? )
oh and chumps, i thought his video was pointing out how easy it was to evade them, DESPITE their faster move speed, like how he crouched for that 1 block by the gate, they stop uncloak and attack, that process takes them so long that they miss, ergo they should have a 'moving' attack...
I think a moving attack would be enough, to be honest. That would raise their threat level considerably. However, Stalker is a Wave 2 specimen so the moving attack should be weaker.
