I saw that Artix posted on twitter a picture of them packaging the shirts a few days ago. You're probably going to have to wait a while longer.
Just checked his twitter after you said this, and I really hope they ship it soon. They said 2-4 business day to ship? I'm eager to try out the Dage shirt to be honest. Not a huge fan of his Legion stuff in game, but damn did he design a nice tee.
Don't forget the "free" 10$ Atrix points. I'm just assuming they are gonna ship the shirts on Monday. I mean are you gonna take a picture of the shirts and say "preparing to ship", but it's been a couple of days and still no confirmation?
yeah Im not saying its weak im just saying that unless all the other skills are about as good as this one it isn't exactly that great of a class as this nuke also adds a DoT onto you, and an 8k crit is not that high as compared to the nukes of the calendar classes (taking a wild guess as I don't really play this game anymore).
