I don't think it should be removed.
It's a great map that allows players to actually sail their own boats. And fight in close quarters with bridges and stuff.
I have played enough times to know that the map is probably one of the best around there...yeah sure sometimes it takes a while to finish a round...so what? Many other maps tend to last almost the same time as this one.
It's just a matter of people behaving correctly and enforcing the rules.
PS: If you see alot of "derp" when your playing in that map, try and message 1 or 2 admins to go there and put some order in the caos
