It just isn't a Slayer map. Two teams camping at their bases taking potshots at each other basically made it Slayer on Standoff on an extreme scale. It might be better for objective stuff (surely it must be), but at this point I think Ridgeline is a Halo 2-style "improvement on the old map in every way" kind of thing.
Slayer as a whole dominates BTB which is a shame. The objective stuff we managed to get was a blast, but it was always punctuated by something like Big Team Slayer on Hang 'em High which is a crossmapping clusterfuck, to put it lightly.
