Except considering that half of the existing quests are bugged with Mari, I really doubt it'll happen. If we get them, half of them probably won't work.
Did they just add quests for 48-65 or whatever? or a bunch of new ones all along the way? I'd love to hit 50+ on some of my chars for valk, but the grind has just been frusterating from 47-50. I just can't take that much maw'ing.
We've got potions showing up as drops suddenly, and it's not mentioned in patch notes or as part of the rainbow event, so I'm hoping it's something that slipped in from Season 3 (in response to the removal of mission scrolls), and that we'll be getting it soon
