It's completely ridiculous.
One of the things they definitely did right in FFXI was to have the whole content spread out between different leves.
So you never felt too "gimped" to do, e.g., the CoP missions because you were downscaled to LV 30 anyway.
What we have right now is that everyone will try to rush to LV 50 as fast as possible, and then
LOLblast through the lower level content.
Lame.
