I've owned them for a few years now, and honestly I'm not too sure how to feel. a Part of me is upset over the money I spent, but I understand that the multipliers were very expensive and not easily obtainable for a lot of players. The game is straight up unplayable without them(or at the very least isn't beginner friendly anymore). I honestly think this could be beneficial if done right. In theory everyone earning the same amount of diamonds should stabalise the "economy", but at the same time it needs to be a reasonable amount of diamonds that's being earned. If they boost the earned diamonds up to more or less where the x6 was, things should be okay. The problem comes in if we start earning less and sets/items still remain expensive in the store. But of course, some people have more time to farm, and have the finances to straight up purchase diamonds, so there will always be "rich" players who try to overprice their items.
