So, graphics and animations have been upgraded over the years throughout expansions. However...one thing remains untouched
Mount animations and graphics
Your character holds an invisible rope or something or is supposed to be "grabbing" the mount and yet the hands are in the air not touching anything.
But that isn't the worst thing.
Literally many mounts I can't use because they give me a severe headache and severe eyestrain. Like...raptors
Raptors bounce VERY fast, so fast it literally strains my eyes and gives me a headache. There is a flaming bird mount from Cataclysm that does the same thing (the non-flying one).
Why have they not fixed or updated the cardboard cutout style animations on mounts? Your character sits on the mount like a stiff robotic cardboard cutout. There is no animation on your character, no realistic bouncing (just the severe eyestrain thing)...like look at BDO, the character rides horses VERY realistically. Or look at LOTRO or many other MMOs with better mount animations. None of them give me a headache or severe eyestrain.
Why after so many years, has Blizzard not done ANYTHING with mount animations? Its the thing you ride on 99% of the game literally...to do any traveling or to do anything you ride on a mount, and its by far the worst looking thing in any modern MMO.
