I've just done the side quest mentioned and it struck me that Flesh Raiders look like really fat and mutated Rakata.. and they were called Disciples of the Rakata in the Mind Prison.. its not a massive leap then to assume that they were Rakata who were mutated over the millenia into their current forms as the Flesh Raiders on Belsavis.

Backstab is as you know - one of the main rotational abilities of the Operative, but I've been having issues using it at times and in more then one situation it's actually led to me mashing my Backstab key, missing out on GCD's in order to get it in which has actually led to me ultimately dying to the elite mob in front of me. What's happening is that the mob is clearly looking away from me, and is facing Kaliyo, my companion, but I can't use the skill, if I then go infront of the mob and try, I do it no problem. It seems to me that the issue is that the mob is sometimes inside Kaliyo's hitbox and it animates as facing Kaliyo and away from me but mechanically, it's facing me and not Kaliyo.. This needs to be fixed because it's annoying, either make the visual effect what matters in terms of using the ability or make the visual effect match whats happening mechanically because it's really frustrating clearly being behind the enemy and having to move to do what a main rotational ability.. Does anyone else have this issue or just me? I can't imagine it's just me as it happens to me all the time..
