Cloaker and a more complex hit box?

[Irish]

was just browsing and came across an idea that i hadnt really thought of before, and noticed i hadn't read anything about. since the hit box for landing damage is more keen on recognizing where the shot lands (ie. head) is it a non issue that cloaking directly up to your enemy and putting 3 pistol shots into his head wouldnt be about 1000x more effective since HS's actually mean something..

in ps1 there was a proverbial "set" amount of shots it took to kill someone, now with head-shots and the ultimate element of surprise im thinking it can make a pretty potent mix. not that its a bad thing...but because of the lengthy time to kill in pS1 the overpoweredness of an invisible assassin was kinda moot..apologies if this was brought up before
