example: On Turn 4, my motion sickness gets me really bad. I still force my self to finish the run, but I have to take a lot of medication. The reason for this, The background is an elevator, and its constantly moving downwards. And no matter what I do, I cannot completely remove the background from my field of vision. I play a main tank for my static, so even if I look straight down, its still somewhere in my vision. If possible, please have a way to turn the background into a non-moving wallpaper or something.
Just focus your sight on the mobs you re tanking (looking straight down is a good idea even if you don't have motion sickness anyway), your action bars (to know if your CD are available) and the small aggro interface on the left of your screen (to know when the next set of mobs will spawn) and you should be fine.
