Having played several campaigns now I have noticed the following during the Replacements Phase.
It is way too tedious to constantly having to drag and drop the replacements unto the different army HQs. The tediousness is augmented by the fact that some corps are intrisic to certain HQs while others are not and could therefore be independent corps. However as the player orders new corps for production and as corps are being knocked out of combat it becomes fast very confusing where to place what again.
Granted the numbers of the HQs help but if a spot that was originally meant for the instrinsic corps to be manned within the army HQ has been replaced by another non-înstrinsic corps and the HQ reached the maximum amount of corps then basically that corps will remain in the replacement pool with no real value. Of course you can restructure the entire armies anew but that takes usually a VERY long time.
So my suggestion is, why not immediately have the instrinsic corps be replaced into the army HQ and lock those spots from the get go so that they may not be replaced by other corps? For example have each armies start with instrinsic corps between 1 - 4. The remaining spots, depending on the country, can be filled with independent corps but the point is that the locked corps will always return to their respective armies automatically.
What do you guys think?
