No, it isn't.
Only if you are a "Pro" and are overgeared, too.
It is easy only if you have 69+ gear.
Beneath that, it's horrible, imho. I had quite a lot of problems there, and I had only 2-3 pieces of 69 gear, everything else was around 60+ (roughly from my memory).
If you had mostly +-60 stuff, you were undergeared.
The recommended gear is 66 (which is really easy to get from oricon)
