Why was the Orange Essence gain lower by half?

As stated in the title why was the Orange Essence gain from disenchanting skin shards lower by 50%? There was no change to either the cost of upgrading skin shards or the ways in which we can obtain skin shards. This seems like a bigger travesty that the changes the Blue Essence(which in my opinion averages out to about the same gain just at milestones instead of a constant stream). I mean there is no logical reason, nor has it been stated by Riot on why this decision was taken, can a Rioter shine some light on this decision?
