The Reinhardt skin is top notch. All of them actually are in my opinion, I wish they gave more characters skins if anything (Poor Mei and Winston get no love).
I'm extremely tempted to use credits to craft the skins right now that I want, but I'm gonna wait til the last day, sitting on 3k credits right now so I can make a legendary if I don't get one that I want.
Must haves skins for me are-
Ana
Reinhardt
Junkrat
Mercy
So far I got Roadhog and Reaper, so that's pretty cool at least. Didn't think much of the Reaper one until I noticed the weapons have candles on them though.
