Should lost ark older dungeons have a nightmare/insane mode

So a lot of the older dungeons once you do both the normal and hard mode your done with them and never see them again. should they add like nightmare/insane mode to these for possible more mat rewards or other rewards. like gear 1300 and up and when we get the 1400s insane mode for them. i know a lot of older MMOs have done this adding harder difficulty for both rewards and braggin rights.

That’s already out in KR. It rotates old abyss dungeons every 2 weeks or something with higher difficulty

yeah thats the trial of abyss in korea/russia

hopefully when it comes out in our version we have the real mechanics not the nerfed ones lol
