The map changes are interesting so far, Solace aside. Adrift moved to snipers at mancannons and an overshield in the middle. Haven is now sword in middle, sniper at open ramp, and conc rifle below mohawk. Exile has a delayed-spawn Incineration Cannon on top of the center wreckage, a Sticky Detonator at Banshee port, and a Beam Rifle in the tank cave...as well as an overturned Gauss Hog in the middle of the map, which I think is a huge mistake.
Looking in Forge, Global Ordnance drop points have been almost completely removed (the conc rifle on Haven is a stacked initial drop with a "never" resupply time with a conc-only GO drop point on top of it for whatever reason and there's a single Incineration Cannon GO point in the middle of Exile, but those are the only two). Looks like that particular "innovation" has been quashed for good.
