I've not moved any goalposts. They haven't given an explanation for why they're increasing the cost, they've explained why they've increased the drop rate so as not to disadvantage players who are starting but none of that is applicable to the increased cost as it does the exact opposite.
Please enlighten me, how would a new/freshly started player be at a bigger disadvantage with the higher drops if they had to pay around 10500 echoes to get all the essences before starting on corruptions with the old costs as opposed to 52500 echoes with the new system?
