I'm not sure if anyone knows but Gaz is planning on getting rid of exp potions. This will coincide with the revamp of story mode which should get you to 60 from start to finish. So I'll probably load up on exp pots before next patch. I cleaned out my stash box this morning and man I'm such a HUGE packrat. I found 3 zolas, helm of doom, 2 batroc boots, 2 masks of algrim, kirigi sword and a kraven vest I didn't even know I had and a slew of other artis. Donated ton of uniques to get more relics but still short of Atlantis. Really wish they were tradable.
