Don't know if this has been proposed or if possible to create an overlay to show your team's strength. At least for assisting in picking which vehicle/mech/etc, whenever I join a game or have to respawn I want to make sure I have the right role fit not just my comfy zone.
Sure, many times the response from the team is "brawler!" when what they need is a spotter running around with a NARC or that APC to sidle up to the LT and provide 'unlimited' ammo refreshes.
At minimum, I was thinking a grid of the team's current vehicle selection to know what is out on the field, weight class, and if any has a C3, BH, Tag/Narc sensors. If possible, one of the 4 roles could be assigned to each vehicle. The summary could just say how many brawlers on the field. Bonus points if a health status was there.
