I used to be a raider, older now, have different priorities in life now. Still love playing games though just can't be online as consistently as many years ago. Personally this format for me is better. Being able to farm the ex primals and o1s and o2s in duty finder/ party finder I find it great. Now thinking of my younger self, that really enjoyed the hard content, using something like teamspeak and being weeks working on a Boss with the same group, I don't know if I would like it. It all depends how hard/rewarding o3s and o4s plus this super savage would be.
But for me now as a more casual player although still like a bit some "harder" content this format is great.
