Just as a quick update... Last night I took down Maat at level 68. Only had to use howling moon twice at that, and it wasn't even darksday, and my gear is still pretty crappy (gremlins handed my @$$ to me so I decided to come back to the AF quests later). Easier than the level 20 trials... so Maat specifically doesn't seem like an obstacle to SMN.
Yep, high level gear doesn't seem like it will be a problem. It's those awkward middle levels...
