I genuinely think hagglefish got more meaningful changes than brinewater despite it being listed as more. Brinewater only really had its side areas in mid changed, and yeah, that'll make neutral a lot more fun, but neutral was never the problem on that map, it was always the terrible lockouts because all your options on defense in spawn are terrible. Realistically unless they change the side tunnel area out of spawn to have acutally good sight lines, as well as not being one way down for some reason, the map will always be terrible. Still I really like a lot of the other map changes, especially umami ruins, which they drastically changed the spawn area to make defending feel so much better, and now I can genuinely say that one at least is a really good map.
