ofc understand, but its to make your farms less expected as ,yes even that the bosses are getting harder, i am thinking of it in the fun way not the Uhgh way, as there will be no new drops, and the types of attacks arent really that effactive, its just like a way to know that you have Reached their "finnal challange" , like a confetti laser from the twins, that retinazer will do as soon as the battle starts, probably the same damage aswell, and maybe even it being on of the destroyer's droids wearing a party hat and shooting rockets that will explode with laser damage and firework effact ,so i ment its not somthing to look forward to as its just to put up a show, but when youre at it, it will feel great ,plus most players wont even know about it until they're at it.
Edit: maybe there should be an item that gives you the ability of fighting 2 bosses at once to either enchant your drop rates, or just for fun. ( more like a crafting station at expert mode or sunthing o3o)
