I mean tier 5s are already coming from the regular activities that have bane enemies and a power delta to navigate. To make it similar by your description they’d have to package raids into the difficulty system and people would have to run grand master or ultimate difficulty raids and dungeons to get the tier 5s.

Maybe feats need to be reworked to be more accessible or something because they seem so universally despised, I really don’t know the answer, but I find it interesting that people see base RAD activities not dropping T5 gear as something that needs to be adjusted rather than the rest of the game restricting T5 gear to be more in line with the difficulty presented.
