Dark rift just ages poorly now since players are given a free PEN armour and stuffs, and it feels more like a chore to do than anything when the box event comes around. My suggestion is to make completing it less tedious by removing the guaranteed CC effect from bosses, removing the i-frames, and of course relocating puturum to a navigable place. Small touches but at least those would make doing this chore of a boss run more pleasant in my opinion.
