The website is deceiving on what you get from a medium bag reward (or any bag I assume).
They are saying :
"Once you have completed one of the collections, you can exchange it for a Medium, Large or Roomy Reward Bag, respectively. Inside reward bags you will find orbs and elixirs to help you in combat."

So I expect to get the whole list of items, because they use the word " and" and not "or" :
"Inside reward bags you will find orbs and elixirs to help you in combat "

When I used the bag , I got only 44 simple Glyph of life.
I'm so not happy.
