Absolutely against call in vehicles. Not that i dont like additional unique units, i love unit diversity. But I sincerely believe they should be locked into tech structure to atleast solve timing issues. Literally every call in vehicle had to be locked into techstructure to not make them broken in some way and overshadow other doctrines which rely less on call ins. Sometimes it wasnt even needed because the unit itself was necessarily strong, but the timing at which it could arrive was insane. This together with a non-tech investment would give the player insane momentum.
Also call in vehicles resulted in imo frustrating games where u have the enemy on the ropes, but then because they they didnt spent any resources on tech, they call in an IS-2 or some mediums, just because they farmed cp's for getting rekt. Call in vehicles should not be a safe net for a players mistake to delay the inevitable.
