They did say dcs wouldnt be nerfed or touched, because of its temporary appereance.
I do get this is a very hard refunding issue: some people just bumped Biggs from r3 to r5. Others geared up MM. Some people spent on Biggs mods, and not to mention crystals to re-roll dcs perks. I suppose some guys got it at first try, and others spent lots of resources.
Probably, a fixed make good compensation should he the easiest, if theres any of course. Some guya will be compensated, others just parcially, probably a small group will even benefit. But if you ask me, anything is better than what the current situation presents.
Also, a clear and predictable response on these kind of "fixes" in the future from CG, would be much appreciated.
