Ace I notice that in your newest screens you still haven't reduced the amount of health around B... I hate to repeat something that's simply my opinion, but for emphasis I just want to add that I think your map would flow better with some changes to the amount of health. Either reducing the overall number of spawns, reducing some of the medium healths to smalls, or some combination of the two, would, I believe, really help Glacier to feel more contiguous.
Right now the sheer number of different health spawns has the effect of fracturing each area into little spheres where, if a person hangs out, they can rely on that one pack. Instead, what Valve showed us worked with Gravelpit was to either put a central health location to bring the fight to a point, or to put many small healths to create movement in an area that is otherwise stagnant.
Just my 2 cents!
