How are XP boost still a thing?
I guess the title says it all. XP boost have been useless for so long I don't know why they haven't been replaced when someone hits a given milestone. I find myself just using them for item use days. Today I used 20 and I used them all up last item use day. I get that they're still useful for new players, but you hit level 60 after just a few months of playing (at least from what I remember)
Maybe when you're uncollected, pull out the xp boost. Maybe change the crystal and you could remove the 2*/3* awakening gems at that point too. I'm selling those off daily.
