My wishlist for Beta 4 consists of a few changes,
Every time a Nuke and Ion beacon is placed the countdown duration is modified by how many nuke beacons have been placed by 10 seconds per beacon.
So if you get 3 beacons at the same time you get 30 seconds extra on each beacon to disarm them.
I think it would help to discourage placing 4 beacons around the base and allow SBH to remain useful.
Of course there is potential for griefing with beacons, but that already happens with the mines.
Also I'd love to see Sydney and Ravenshaws do more damage to armored vehicles.
Maybe a 50% increase against armored targets so that both teams have a reliable tank killer.
Right now nothing short of several EMPs and 2 Airstrikes can stop a Nod or GDI push into a base with tons of flamers or mediums.
