Don’t forget that in patch 2.3, you will be able to purchase potions with 50 apexis shards that will be equivalent to super healing or super mana potions. We are thinking of making them usable anywhere, so that should help too.
I am personally glad Blizzard is considering this. The cost of super healing and super mana potions is outrageous (up to 50g with a few sellers) on my server. I just hope with 50 apexis shards you get a stack not just one.
