It'd be great if there was an overall map. Spotting friendly vehicles would be easy
as it already is easy on the minimap due to their shapes. However for classes, I'd
propose the following.
Group whats possible, f.x. engies: techs/engies, snipers: marksman,500sniper, 1ksniper
machine gunners: soldier, officer, minigun users, mobius/mendoza(?)
anti-vehicle: grenadier/flame troop, rocketlauncher, gunner, sydney/Raveshaw
and so forth.
Now on the side of the overall map there'd be a colored list:
SBH: 3 (in red)
Snipers:2 (in green)
engies:5 (in blue)
etc.
Now the dots on the map for players would have a corresponding color
to their class.
Being able to access the overall map constantly feels too op for me. It's better
to have people communicating so having the option to only view the overall map
from the terminal would be balanced as far as I´m concerned.
