Riot map designers come

Haven - needs a map rework they need to change A sewers and C long cubby and B entrance cubby remove the wall on backsite of B and add a box or something
Ascent - for A site change wine make it a little small, for pizza (mid) close that gap or remove that box where people hop on top of it, B site logs close the gap or add a small box, B site boat house there are 2 arches you can get into remove one arch or add a ratty corner catwalk cubby close the gap or make it small

Ascent and Haven are the only maps they havent made a rework on since the game released (i could be wrong)

if im missing any maps let me know

Can i read even if im not a riot map designer?

Lotus hasn't been touched yet. Although there have been leaks about Lotus changes

haven and ascent are only decent maps
