It’s kinda the nature of the hamster wheel, most of your previous tier gear gets replaced by the current tier, it takes an exceptionally strong item present in the first tier to get people to run it in later tiers
DST and thunder fury are two examples and that’s why binding runs and gruuls happen the entire expansion
You did something intelligent which is asking the question of is it a problem that old raid tiers get largely irrelevant (hence why people stop running them), that’s a very good design question to ask/answer so I’ll promote you up from baboon
