So I've always seen pokemon as a server that does and should have a very high standard of map quality. And looking through that lens, I'm gonna comment on each map individually, having played them all at multiple times.
Saffron: -1 . Before you get to silph co the outside area is oddly proportioned and looks bad. So basically the map should be called silph co, which is just a tower you (I believe if I'm remembering correctly) teleport from floor to floor, which causes obvious problems. And even if it's stairs and I'm dumb the map is just aesthetically meh and it just being a tower would breed toxicity.
Pokemon stadium: -1. Not as much to say on this one. It just isn't noticeably pokemon outside of the map layout and file name. Just doesn't really meet the standards we already have.
Victory Road: +1 . We had this on rotation history, and had a ton of trouble with the balance of the final cap. That was literally the only issue. Gorgeous map, well made, and without the cap enabled it's only issue no longer exists. 100% meets our standards. We should add this ASAP.
