While Mercy looks pretty I find the visuals distracting as hell. As with almost all 343 maps there is too much visual noise. I think I prefer the clean visuals of the original and it's nice to see it recreated here.
While I do agree that 343 puts way too much visual distraction in their maps, I also don't like maps that put barely any visuals in at all. Especially to the point where you can't differentiate locations.
Oh yeah I remember how they had to add forge lights to both sides to help address the issue. I really hope they find a nice middle ground for future maps.
