I think the randomized loadouts would have to include a drone operator and a breacher, since demolitions and reconnaissance or crucial to so many missions— with the other two being chosen from the remaining roles (including two generic assaulters).
Yeah, finding a way to make sure all the needed bases are covered while also adhering to the "totally random" scenario would be a little tougher.
I feel like if everyone wants to do totally random, then there should be the opportunity for a squad to be missing certain items (no C4, no Drone, no Sniper/LMG, etc). Maybe you end up with 4 AR guys? Part of the challenge could be making missions work while also randomly (purposefully) handicapping the squad. Everyone gets grenades, so you could still knock down doors if needed. Vehicles/etc will still succumb to focused fire.
It would also be fun for everyone to be required to get their main weapons off enemies. You could start everyone with a pistol, or say no weapons, and you have to melee someone to get their gun.
If you don't want to get that crazy, just doing 'role' assignment would also be fun, either rolling for them or letting people pick. Maybe roll within the role? So you get AR/Grenadier.. then there is a roll to see which AR you get, instead of just picking your favorite. Same with Sniper.. so maybe you don't get to use the HTI or MSR.
It would also be good if you could build in 'tiers' of complicatedness as well.. so you could do a 'lite' version where it's just basic rolls and everyone gets to pick what they want, and what they want to use, a more in-depth version where you have to roll for your guns, and maybe a super in depth version where all the equipment is doled out, no respawns, everyone matches camo, etc. If you could come up with a sliding scale, it would allow the system to be used by more groups, more often, instead of a single rigid policy maybe?
Some things just don't work well due to the way the game is setup. Getting thermal instead of NV still means you need to cycle through NV to get to thermal (or vice versa), and while yes, you CAN, it's messy. I'd prefer 'advanced vision modes' or something be included as NV+thermal. Separating the different items is easier, since you can cycle through the modes without committing to them, though I wish you could disable them.
Something else to consider if not every player has unlocked everything (yet) so people will be on different levels with regards to VHC damage/etc.
I don't know I'm just spitballing. It would be nice if the game let you do this as part of the game, but I'm down for trying new things to extend the life of the game until DLC and/or PvP comes out. Executing a mission like a well oiled up men's gymnastics team is amazing.
They really should add rappelling ropes. Imagine the fun you could have with helicopters, rooftops, rock formations......
The helo's even have a spot on them for a rope to attach! Maybe DLC will have it? Would be perfect for those quick entry/extract missions.
