I'd like to know what exactly is Relic planning to do with the US ability to decrew vehicles, because it really seems like they haven't thought through how the ability is supposed to work or be of benefit outside of single-player, and are slowly removing it from the m.p. game.
Is decrewing the priest still allowed? Because this would be inconsistent with Relic preventing decrewing of the calliope for cooldown reasons.
They aren't removing decrew from the game. They removed it from two units for very specific purposes. Pershing so you can't get around the 1 unit limit. And calliope because it was being abused to get around the upkeep cost.
Priests are much cheaper then the calliope and less powerful, so upkeep abuse isn't as much as a problem.
