The Fractals are fine for me, new one was amazing, my problem is these cancerous instabilities, basically "everything kills you in one hit now, yay".
It's one of the reasons why Block and Barrier are the new "meta" instead of healing, you can't heal a dredge outflanking you while you have frailty, but you can block that 20k damage you will receive hehe, i even remember a time when you could easily do T4 Fractals without any healer or support, even with pugs, used to do that a lot, now it's next to impossible to do.
Like, i have no problems dealing with those (except that trash combo of Afflicted in the last boss of Aquatic), but since i only pug, it became unbearable to do them for me, and since most of the "veterans" have left, you have a lot of new people, so you have to go from group to group, failing a lot, till you find the right one.
I stopped doing them like 3 or 4 months before the new Fractal, then it launched, i did it a few times, even at T4, but stopped for good since then.
It's a shame, my favorite piece of content in the entire game.
