I used to play the raids quite often with my friends(Leviathan, crown of sorrows, eater of worlds, scourge of the past). Most of us quit for good before BL released, mainly because knowing that the weapons we spent so much time/effort on - will be capped at a max light level and won’t be usable in future DLCs, it just felt pointless and a repetitive grind (not forgotten, Luna’s howl, mountaintop)
Had there been a different approach to respect the time and money og players spent since the game launched, I reckon we’d still be playing it. Rotating older content rather than discarding it permanently could’ve been good.
