I disagree with your point about "making bosses" easier. As many have mentioned above, PVE content has to be challenging, otherwise it's no fun. I recommend you review your strategies if you are failing to make progress on this type of content, because that's the fun of PVE, creating new strategies and having fun with new challenges.
P.S.: There's an event going on, take advantage of the Christmas event to have some fun!
