cobalts have now been wayyyyyyy over priced for what they are, you have also devalued golds a ton. i know i am not the only one saying this but you need to make cobalts cost less, sure im fine with this new system but you do need to rethink and rebalance the costs of fragments needed. Yestarday i put $20 on steam to hope i could spend a little on dirty bomb and get a cobalt card for a merc and buy a weapon kit aswell, you know giving something back to the devs then i realised all the time i spent on getting rid of cards and getting rid of cards, that thinking about it i probably shouldn’t of got rid of, like some of my golds and even silvers and bronze, this was all useless because all i had was 3,600 and i need 20,000!!! i sure would of gone and spent money on the game but i had to rethink that issue, say if i didn’t have that money on a later date and i wanted a cobalt i would need 50 freakin thousand credits!!! for someone who still has one merc left (thunder) and i not really saving up for him i use to trade up cards for other mercs etc, etc and never have to worry about saving that much up, all i would do is save up 15,000 - 25,000 and then from there decide what to do. going back to my situation, i thought well golds aren’t that bad of cards, sure they aren’t cobalts but they will do, then i realised oh, i need 25,000 if i weren’t to pay so after 30 mins of deciding i realised my money would be better spent on/in another game, this makes me sad that this happened to me, sure it has happened in other games but it is the first time in dirty bomb, i am sure others are thinking the same way and this could badly affect dirty bomb for the worst.
sorry about ranting on everyone this just needs to be changed
