Not interested in loot boxes and MP myself
Loot boxes are loooong gone. The Epic version of the game comes with every skin and hero unlocked, weapons and cards still need to be "earned" through game play.
The new supremacy mode is actually rather fun, all the old complaints about gameplay still apply (save for spawn camping, which seems to have been eliminated). Maps are gorgeous, though.
Single player (and I use the word in the loosest sense of the word) campaign was nothing more than a tutorial for MP. It's not worth the ware and tear on an SSD, seriously!
