I can personally say that I've been enjoying raiding without world buffs so much.
Not only do you avoid the stress of having to get them, but it reintroduces a sense of danger and excitement to raiding - wiping on Naxx farm right now feels way different than it ever did to wipe with full world buffs in BWL/AQ.
Finally reaching Naxx has been a great experience, so a big props to the Elysium team for that in general.
This is unlikely to ever happen, but I have to say that I would almost prefer for them to be disabled for Naxx permanently.
