@Anarchy-Marine Woah thats some ancient change you mention on Warframe.
I think you misunderstand then because on Warframe its in relation to melees attacks only, "align attacks to camera" and has the option to disable it, this was quite successful afaik, and it also has the "Camera Tracks Melee Target" and "Melee Auto Targeting", these last 2 are the most disruptive ones on warframe but the options are there.
PSO though has soft target locking already for ranged weapons, target finding, and melee animations root the character AND camera as well on Z (manual), which doesn't happen in warframe where you can for example adjust an on-going vertical melee swing to hit the head of an enemy with "Align Attacks to Camera".
But for me what would benefit the most from Aligning isn't melee on PSO, but ranged attacks because of the target finding it already has, if the character is facing the direction without being in manual. It would allow for side movement without changing the attack direction or doing a hard lock on. It's not like I am ever trying to hit something that I can't see on my screen, ie camera.
I too was searching for this on option much like OP. Wouldn't it be nice if they added the option? It would be more dynamic than depending on hard lock-on on one target with Q, but less burdensome than Manual with Z. Somewhat in between?
