I think that Mjolnir won't be just another skin, due to the fact that they said it is a "functional weapon skin", and it "packs its own special powers". I'm pretty excited about it!
Aside from that, it genuinely makes me sad when I see how awful this community is. Complaining about literally anything they can find. They could probably say that they're starting an initiative to clear out every single bug in the game, and there would still be people complaining about not getting 2x rates for that weekend or whatever. How about y'all learn to be grateful for a change, and appreciate what you have, and what you're getting, rather than what you don't have, or not getting.
