What's wrong with it? Contestable expansions and no major choke points, these are good things. It looks kinda similar to Crimson Feud to me but with less mass, and that's your favourite map.
My vote would be to have some team game maps, there's a skill to playing on them that is every bit as legitimate as being good on other types of maps.
Morax, I know you want spoilered tangent contents kept out of here, but it is relevant: if there's no way to stop one player being way more prepared for a map than the other, then I actually vote for none of my (or anyone else's) suggested maps to be added and for a massive purge of the Bo5 pool.
