Hello. We, as a tankers, need to have option to CONTINUE micro-upgrading hull/weapon Even when we reach higher rank to fully unlock next MK upgrade. Exmpl: I have micro-upgraded my turret to mk1-8 and then I reached rank and now I cant micro-upgrade it anymore and have to pay FULL PRICE for mk2 upgrade even when I spend like 5k for that upgrade but now I have to still pay 7k for like I had mk1-0. Or make that price have DISCOUNT (of the amount that I spend to micro-upgrading (not speeding up)) or give players CHOISE to choose. Thanks. Best regards, LJR353.
