Hello fellow tankers: I am a Lieutenant-Colonel playing with M2 railgun. I have my weapon upgraded at level 20 out of 50. i am pleased to be able to destroy some Hornet M1 and practically all Wasps M1. Only the upgrades are expensive (the 21st is 7000 crystals) and I am wondering if it is worth to continue upgrading my weapon. Is the total price of all micro-upgrades inferior to the M3 upgrade price? Thank you for your help, Jeff Parker
