I'm going to have a long list of suggestions, just remember that's all they are and you have a very good structure.
• The map is very center strong, I think this is caused by the two mega armors and Nex and quad all being there. Try replacing the megas with a 50 health on one side and a 50 armor on the other.
• With two Rifles on a map this size, I would consider replacing the Nex with a RL.
• The quad can be reached by anybody who just happens to be there at the right time. I would put it next to the ceiling so a laserjump is required to get it.
• If you add the RL, it'll need ammo. You could put all different kinds of ammo on the shelf where the 5hp healths and armor shards are, moving these to the base.
• I don't think you need the angled invisible jumpad at the top of the shaft. Sometimes it malfunctions and hit you twice or something. Just make it like the jumpad in Stormkeep, the one next to the strength. Put the target for the bottom jumpad on the edge, so it will shoot you up to that and then your momentum will carry you past the edge.
• Something to let people know that there's a jumpad there. Doesn't need to be a model or anything, maybe a grate or a weapon spawn circle.
• Some ramp trim would be nice. Texture it with steel or wood, something to break up the stone.
Again, just suggestions, what I would like to see. Could be personal preference.
Really like the triangles in the middle.
Ok, tried beta 2.
Managed 5.58 cap.
Two RLs? KaBlooiE! Isn't that a bit much?
