Good evening (actually in germany it's middle of the night about 11pm )

I really think that this could be possible, haven't seen naxx and I don't know how much Micromanagement is needed to do Naxx (Movement/ Target Change etc.).
I guess the difficulty is comparable to 10 Instances (Classic) Everyone is was going with 8, some did it with 5 (as the cap was still 10).

Greetings,
Shaitan
