Mathematically, the difficulty should adjust downward weel before this. Electroneum has posted an update on they're Facebook page that addresses this part of your statement.
When the monero forked I knew it will not be easy to mine until the difficulty adjusts but I supported the coin
now that the ETN forked i did not give a f**k becasue that guy Richards Ellys or whatever his name is, turned out to be assh**e (sorry about the stars, i did not read forum rules so i don´t want to get banned). It will take 720 blocks to adjust difficulty, how many ETN mined after the fork, 30 so far? And that is with help of Nicehash, probably the devs spent small percentage of money they earned becasue small part of them was feeling guilty
