This feature would give players the option to scale down their job to fit the designed difficulty of the raid and double their maximum challenge raid content for 1.18. Many of us can't bring a class to raids that are of an appropriate level any more, and it would help perfuse those required 4 and 8 man parties with a good balance of jobs instead of a mishmash of what is available.

This would also solve about 40% of the raging upon hearing news that the raids aren't capped.

A level synch for raids would be the new easiest, most efficient solution now that level caps are out, especially if SP gains are significant in raids.
