That’s the thing. It’s not just “wow, I can see more, this game looks great!”
Some people (myself included) get incredibly sick from games w/ limited FoV, and are sensitive to the quick camera turning or camera bouncing. Luckily WoW is not one that does it to me, but there are many FPS I can’t play for more than an hour without experiencing terrible motion sickness. As it stands, I play WoW at maximum zoom so I don’t have to turn my camera as much.
FOV increased to 120 was a huge win for accessibility, and should have remained in place. If it’s an issue in 1 specific subset of playstyle (arena) then it should be fixed in arena to 90 and 120 in open world/raid/dungeons, etc. Shouldn’t have to tune something in its entirety around an outlier.
