I have these issues with the mount:
The mount often clips into walls.
It’s hard to turn around.
The barriers that blocks the way that you need to dismount and destroy are only really annoying. My anger just builds every time I get stopped by one until I eventually alt-f4.
The cooldown is 5 seconds to long on both the mount and the dismount attack ability.
The asymetric camera and the level of zoom makes it annoying that the speed of the mount is tied to cursor distance. I see the idea but make the max speed to distance ratio alot smaller. Small enough that you can run south and have your cursor above the abilities and then some and still get max speed. Also WASD solves this (aswell as alot of other things).
To me, all of this combined makes it really annoying to run around with the mount. Please fix this yesterday and lmk if someone else agrees.
