Where is the fun in having everything handed to you just because you showed up to participate? Isn't it more fun to have to work/struggle a little so you can enjoy the feeling of accomplishment when you clear it?

I can't think of a single MSQ instance that needs to be nerfed. Making any of them any easier would turn them into LITERAL faceroll instances. Aetherochemical might be a little tricky but come on, it's the final challenge, it's supposed to be a little tough.
