I would rather have constant cosmetic promos than xp promos. Lets face it, Treasure Hunter isn't going anywhere.
I do however find it cheesy how many stars you get when opening chests. I'll admit I purchased keys to unlock the three titles and outfits I genuinely liked. I received too many stars compared to Ghostweave. _.•´¯`•._.•´¯`•.* D E L A Y *.•´¯`•._.•´¯`•._
