Honestly, I just came from PoE to this game. (The one month flashback league was f’n awesome) But I have no idea how you think this and that game are alike. Honestly though, it would make a great addition to endgame content for any MMORPG, but at the same time that’s copying another publisher’s ideas so obviously that’s not good. 
However I think every MMORPG should have some sort of randomization for endgame contents though, it keeps you from getting bored of doing the same thing over and over again. I’d purpose doing something more original of their own however it seems the support for this game is incredibly low, at least for the English version.
