It doesn't matter what changes or gets fixed, there's too many differing opinions and too many people playing for nostalgia for anything to work perfectly. Best recommendation is reverting to whatever had the longest calm, and improving from there. I've been through every map since summer 2017, each one had a map change suggestion post. This isn't new, nor should it be something garnet should be shocked about.
At the end of the day, the community/players will continue to drive the gameplay meta, not the map, which makes me think the issue is never really the map, but how the players use it to their advantage to piss off the other side long enough for them to request a map change. Just my two cents.
