I personally dislike the changes, although I'm gonna have to say Goblin made a good point, there needs to be some forts easier to take than others.

Since the original integrity of the fort has already been lost, here is what I'd like to see:

Downstairs: centre square area widened, spawn points changed to top corners of that area. Bottom two staircases widened to make one larger (harder to block) staircase. Those little island walls either removed at the back or reverted to how they used to be. Only one health orb, and make the entrance to it smaller. Where the two secondary orbs were at one point place health pots and leave the staircase as is.

Upstairs: nothing at all.

Outside: Widen the area between the trees and push the statues back to stop people getting trapped. Maybe opening the area behind MoD again, but that would really only be for aesthetics and nostalgia.
