When given a choice, I would always go for new units rather then old one.
Its bland enough already how everything US is always shermans and everything wehr is always P4-6, if other factions can be improved by variations, I'm all for it
There are plenty of other vehicles that could be used ... but simply using a tank that was never used and calling it a day is easier I guess. Just look at the Wirbelwind. They could have used the Mobelwagen (as Crecer13 pointed out) but apparently getting "new units" is only important when it allows for stuff to be used that was never used
CoH2 soviet campaign was pure fantasy and stereotypes and nothing was wrong there, nothing will be wrong here either.
Ah yes. The campaign of the last game had historical inaccuracies (that people complained about a lot) so let's just throw historical accuracy completely out of the window instead of improving the situation ...
like I and others said: If Black prince is in game then why not add Maus?
