I'm trying to make sense as to why a unit that's just nearly the equivalent of a Panzer IV is 40MP and 15fuel more than it and 20MP and 10fuel more than the dual call in. I understand the dual call ins being more of a economic deal as a result, but the single unit comes rather late at 9CP. The recharge time also takes awhile for the single T34/84 to be an effective presence on the battlefield. I would've rather float and have the dual call in than the single unit, especially since the recharge time is nearly identical.
It's a kind of magic.
