This could be used as like a base point idea to enable weak/normal/strong versions with 25%/50%/25% drop rate chances on items by expanding upon rare mob loot tables.

It's not so much that it's needed, but it is a potential way to enable players to enjoy the content that is there for longer periods and ease their way through it a bit more fluidly while lessening the dependance on servers needs for boxing/botting in order to do instead you'd have a avenue to farm locations longer, but be more rewarded for it overall and I think the real bread and butter of the game is the solo and group content while raiding is sometimes more challenging and can be fun it also can be more tedious to synchronize.
