LinkThree of the four vehicles are multi-person (2 or more). The fighter is the only single person vehicle.
LinkRight now all armors have 3 weapons. I thought I would hate that actually, but it seems fine to me when I'm playing. I also wouldn't mind seeing 2, 3, and 4; although 4 seems like too many now that I've played for a while with 3.
When I think back to T1 or T2, the only thing I ever changed on my heavy loadouts was my pack. 5 weapons meant I could have disk, chain, plasma, grenade, and mortar in T1, and sub the missile launcher for the plasma in T2. It's really a ridiculous number of weapons in that light. Only having three makes you decide what you're going to do in Heavy, and it also limits the damage a heavy can do at the enemy base because they are more likely to run out of ammo.
So at the moment our thought is three weapons for everybody. It's not set in stone, but I think it's likely.
