Please keep ambush pass in. This is personal, but I've gone to hate the maps I mentioned above with a passion. Ambush pass, I like it. Other maps are in much longer so they've got to go.
I'd like the same poll about Esgaroths Ruin's: http://www.strawpoll.me/12464661
As for crashing waves, it's just weird. I'm not a fan of Roanoke as 1v1 (why not? It's got loads of mex spots all over the place and I don't like it?) but that seems a much better 20x20 navy map to me.
Also, the Nilfheim thing. South can get a double adjecency factory at the two mexes near the upper ridge and north can't. I would fix it myself but the editor doesn't work on my laptop.
