Here are three suggestions, the last I think it the only one not mentioned so far:
3. Game>Options>Combat Highlights>Circle.
What this does is instead of having to click on the enemy pixel perfect, you have an imaginary cylinder around all enemies that encompass the circle added to their feet, which makes the hit box much larger and it doesn't sway.
3. Doesn't do that for me. The hit box seems pretty much unchanged. I just did the Valeanna fight and was chasing around the earth elementals with my mouse like always before.
My apologies, when I tested initially I would have bet the farm I wasn't putting my pointer directly on the enemy and now had a full invisible cylinder around them, I specifically tested that. But your questioning, I went back and no such thing, I am having to click on the enemies pixels. Strange.
Brightest side I can throw out there, that is real player click accuracy that is now part of the games hit accuracy.
