I get what u saying but Heroic raiding is a "casual" content that u can do with a barty of ppl between 10 and 30 ppl. There are guilds that only do Normal raiding and consider Heroic "hard" and i understand that, even though i think Heroic is not difficult if u do mechanics. The moment u need to overgear the ilvl from the raid itself its the moment something is wrong...I used to do HC with Normal difficulty gear and dungeon gear and then moving to Mythic or even before full cleaning Hc moving to "fist wing" of mythic to get best gear but only to clean Hc in the first 2, 3 weeks (as a,what i call, normal/advanced?¿ player). If ppl choose to do 15 to overgear it's their "right" but the content its not designed to be beatted "legacy" mode. I've seen ppl with 3000 score that cant beat heroic bosses but obviously the problem is that they want to play the game statue mode and in m+ sometimes they can do that. I think the solution will be basically increase the difficulty of the mechanics not the "scaling" so that way u can differentiate inn a , maybe, more right way.
