I play Ninja. A lot. And I can't say how many times I got clipped by an AOE because I was panic slamming Shukuchi trying to get a teleport out of danger, only to fail because left click also rotates the camera. This also affects basically any job that has an AOE which doesn't center on them (such as SMN and WHM).
So I propose one of two solutions to this (or maybe some combination of both):
1) Prioritize clicking down over rotating the camera
2) Let us toggle left click camera rotation off
Thank you for reading. Offer further feedback or stories down below!
May the rotations ever be in your favor.
