The prices of weapons and their modifications need to change because they were set quickly and ad hoc, we all know that (illogical same price for Tier 3,4,5). My proposal is that the price of weapons and their upgrades should be determined not only from the tier, but also from the quantity and the actual role they played during WWII. Let the purchase of common weapons not be hard for the casual player, if you want to rob players of silver, let it be by buying and upgrading: rare weapons, prototype weapons, wunderwaffe, mock-up wooden Japan tanks and other junk from Wolfenstein.
This will more variety to the game, players will be able to equip their troops with more available equipment (more semi-historical, on occasion), not just the same, best equipment as it is now.
Bad idea, many prototypes stuff are added because of balance. This will cause more imbalance between faction, for example Japan are doomed because of this.
No it will only increase the gap between wealthy player and normal players since wealthy players can afford better prototype weapons.
Pfft no. Germany’s most common firearms were the Kar98k, MP40, and the MG’s. Every single other gun in their tree are either earlier versions of the MP or experimental/late war garbage. Or Czech/Polish/French/Russian/etc
