You mean this stats reroll crap? Who needs them? Nobody i think that was an Idea from Plarium to get more money but failed like that xp barrels... You think i have ever seen an offer for xp barrels? lol
Well, these ones were free and for some people it's worth a shot, on say gear like 5/6* legendary speed and a few other sets where they had some 3 or 4x rolls that went poorly.
