Dear Devs, dear community, i think there's a big unbalance problem at the moment in the game. you absolutely don't know how to spend t1 currency
almost impossible to find some planar framents type

most of the people, me included, never seen ONE death crit power fragment since launch, that was Autumn 2016. 1.5 YEARS and no ONE drop, this sounds to me that there is something WRONG.

i'd like to suggest a very 'clever' fix : allow buying the fragments chests with Ethereal Shards (t1 currency), and this would solve 2 problems in 1, because when you are gearing for t2 raid you have plenty of t1 that you absolutely don't know how to spend.
