My personal wishes for a future wargame release:
Continue with cold war era as it is now.
Lock things more into specializations. Ie. super heavies locked to armor decks.
Certain powerfull attack choppers locked to moto decks or whatever.
As it stands, specializations are usually used for cheese such as israeli mech or entente mech.
It would open for more variations in the meta, due to every deck having significant disadvantages.
Remove General decks. Its too difficult to balance.
Lock CERTAIN prototypes to national only.
Now the question is, but how to make sure that not only the big factions are played? Well thats where the coalitions come in. Although unable to use certain prototypes, have far more flexibility.
Certain nations would close to never be used standalone, such as Denmark, but that is on the other hand very realistic.
All players into the same pot, as a starting point.
Matchmaker quicksearch function as the primary means of finding games, that can search multiple parametres at once: 1v1 2v2 3v3 etc.
All matches gives elo, automatically - you cannot matchmake without getting or losing elo. Map veto function.
ALSO: you should be able to search matchmaking in timeframes. So that if you tick off the pre 85 or pre 80 box, only decks with those limitations are eligeble. This would split the playerbase a little bit, but it is such a shame that historical gamers cant use this aspect of the game in an automated way.
I would like to see a more diverse map pool, such as middle east, eastern europe, asian/pacific.
Also more interaction with the terrain, hills, weather, rivers, bridges etc. As it stands, terrain rarely plays a part. It would be awesome to see marine type decks at an advantedge on certain maps due to amphibious vehicles.
For factions, I think it is obvious to include the middle eastern nations. Iran, Iraq, Egypt, Jordan and Syria. Although limited changes to the equipment (if any), it would really round out the games reflection of the hot/cold war nations. It would also allow for a more diverse map pool. Golan heights fx.
Although I like the idea of pioneers doing things such bridging / bride reconstruction and/or mine laying/clearing, it may prove too diffcult to carry out in a meaningfull way in the game.
In terms of unit / world interaction, I think Steel Division did a lot of good things in terms of how units move around. It doesnt have to be much more advanced than that imho - with one exception. Embarking and disembarking transports would be amazing to have more organic. Although I understand that this would be insane amounts of work due to the sheer amount of different transports. so its a luxury item rather than a nescecity!
Generally, wargame is the best PC game I know and I guess not too much should change from that. The learning curve just needs to be adjusted so its easier to understand for new players. Marketing needs to step up their "game"
