Interesting how the command Panther and P4 don't have any penalties (other than the P4 having a main gun that shoots only HE) but any UKF command vehicle MUST have penalties. At that point, why not just have a 50 muni loiter plane ability?
Another conspiracy theory that does not hold water.
Compare the 3 command vehicles:
PzIV:
CP 9
Gun nerfed compared to standard PzIV
Aura 80% received damage
Command Panther:
CP 11
+10% speed, +20 sight radius to nearby vehicles
Main gun AoE damage 1/0.15/0.05
Command Panther mutually-exclusive with the King Tiger (similar to JT/KT restrictions)
Costs allot more then Panther
Command Vehicle
CP 2
Penalty -50% accuracy +100% reload time modifier.
Command Vehicle Aura
Infantry: +20% accuracy, -20% cooldown, -20% reload
Vehicles: -30% reload, -30% cooldown, +30% accuracy, +15% penetration
"Designate command vehicle" is simply superior.
