Item Grind Spots

Anyone know if someone has created a list or areas that the mobs have high item drop chance or can drop items and there are a lot in the area. NOT XP GRINDING cause I know most xp grinding spots the mobs don't drop loot but I want to know good areas I can put a lootbonus set on and get a lot of a certain armor or weapon Like SteamJet Walkers Can be dropped from mobs in the level range of 81-91

 

Any mob in that level range have the same chance to drop the said item, no?
Unless they make different mobs/variant drop different loot pool, this should be the case. If not, then I have no idea

The only thing that differentiate specific mob to drop exclusive item are Altar Bosses, Relic Mobs, etc.
