Donno mate, what about killing a mob directly pops out its loot ? :) I am playing a game right now that works that way and it's kinda good. It's personal drop but all the loot comes out and u don't have to target click the mob and loot it also there is an item that can auto loot if you set it to do this and this very item can be customised to auto loot or auto not loot or even auto dismantle items the way you want. Just like this: i am looting legendary items for my class in the same time i am dismantling legendary items for other classes because I don't need them. :) So if this can be done with an item why not with a game option ?
Auto loot is just something that we need. If you don't want to have it just switch it off but if you want to have it just switch it on. Devs should work on this for sure. :)
