I Think new maps should be added, but I agree with Teeth, the maps you've suggested are kinda shit and gimmicky imo. The bridge map with the gap was the dumbest shit ever, everyone just stood on their side looking at eachother whilst ranged had a good time. Arena might be a fun map sometimes but lets be honest, its fucking tiny and if theres more than 40 ppl on its just a clusterfuck.
There are good maps however that were removed from the map pool, might be Worth looking at what maps we used to have and reevaluate if they're good or not.
There's a few circle maps in the roster right now like the Church one which in my opinion is frikkin horrible and should be removed or changed. The journey to find your opponents isn't too exciting.
