Do lesser uniform upgrade tickets ever go on sale, or are they acquirable some way? I accidentally used my Advanced Upgrade Ticket (from SL) and looking to insta upgrade to mythic.
Afaik the legendary-to-mythic or mega uni ticket is ever on sale not the lower ones. But i got some lower uni tickets from aprils fool event chest, you might get it from similar event.
i heard you can get one from spidey enemies in the special missions (finish all the challenges for that pack iirc)
