What Do We Want as Maximum Character Power Scaling?

I still play FFXI because of the 'lower power scaling'.

But in order to do it, I have to 'refuse to level past 90'.

Even then, the general world content is still not a challenge, but lots of other things are, and level-capped content exists.

I'll play if Ashes is similar, and probably go back to playing FFXI if it isn't.

Here's a prior thread discussing similar concepts, with a more concrete scale that covered the subject rather well.

I'm in the "Final Fantasy XI" camp. I want at-level overworld monsters to be individually interesting, and bosses/raids to require proper group skill and coordination.
