I’m just catching up on these posts so apologies if I missed anything.
I’m not opposed to the changes proposed around cruisers and Battleships and I’m curious about how the game plays with more of them on the board. Although I’m not sure what the price point is that makes them more common. Air has the advantage of being relevant to both land and sea whereas naval has very limited relevance to land, although I suppose that is also an argument to change the relative pricing of naval units relative to air. And at least with BM the marine unit mitigates that somewhat.
For air, while I’m also not opposed to trying something I am more hesitant about reversing the relative costs of figs and tacs/bombers. Figs are definitely the most common buy but, unlike naval purchases, I do see all 3 bought regularly. And I think because figs are the defensive unit and tacs and bombers are offensive there is some logic to the current relative costs . The axis need to play offensively (and in my experience they are consequently more likely to buy tacs and bombers) and the allies need to play defensively for much of the game (and so primarily buy figs until late game if they have managed to go on the offensive) So making offensive units more expensive does help mitigate against the axis advantages and changing it the other way might impact game balance to the benefit of the axis.
