Olden isn't pugged because it requires teamplay
I think having an even number of maps is a really bad idea when it comes to tiebreaker maps. Rankin is really good so should be in.
I haven't played the latest version of bloodrun, but i'm not sure it was league level the last time I did.
MountainMan did feel quite frag heavy, but it hasn't really been tested enough with high fragging teams who know the map to determine that properly - just the feeling I get. I liked it personally but i can see why some didn't.
Never played Tempest low personally so can't express an opinion on it but I wasn't aware there was a huge amount of demand for it being changed.
