k, some quick opinions (not influenced by the topic... I haven't read any of it

)
Sawmill: Beatiful. Love it. Best arena map ever. It seemed huge at first - and it is, probably best for 12-24 players, nothing below - but that doesn't bother me. I like big arena matches. I obviously love the rain, and the sky is beautiful. The one thing I don't like is how the spawn is closed off... I just don't see why they did that.
Nucleus: Looks ok - mostly thanks to the modeller, of course. I don't like how none of the combat is focused on anything at all. I see how they wanted the doomsday device to be the center, but it's obviously not; everyone (understandably) hangs out in the tighter corridors (snipers are very powerful in the outer arena, they either wounded me, killed me and/or did the same to my teammates immediately after almost every single round start), which feels weird. Nucleus isn't what I had expected, because it all boils down to a couple of corridors. Oh well, it's not terrible either.
Pipeline: Part of me doesn't like it very much, part of me is very interested. There are a few niggles with the details that I don't like (every out of bounds area is black... it's almost claustrophobic), they haven't clipped a single staircase, the explosion sucks... Stuff like that. Not the end of the world, sure. And there's a lot to like. I'm surprisingly happy with the gameplay of the first two stages (lots of side routes ensure that there's little spam).
However, while I quite like the first two stages, stage 3 is pretty terrible in my opinion. The cart rolling all the way down again is so depressing, it's just not fun at all. As opposed to stages 1 and 2, spam + a couple of snipers wins the day here. What were they thinking?
