I do it because I have beat it the "correct" way a few times and now its about time management. Im old and have a family so I rather push them both off in 5 mins in order to spend my time doing other things. Especially since I will get another sparrow or shards for beating them instead of something worthy of my time unless I get lucky. Its about to get patched anyways and we will all have to go back to the normal way so for now might as well save the time and energy for when I need it.
