Can you elaborate more on the situations in which you would wear gear outside the favored classes? I'm trying to understand if it's something you'd do intentionally or unintentionally.
For example...

Intentionally: For RP purposes, since you wouldn't receive any worthwhile bonuses.

Unintentionally: You're gathering materials on your low level DoL class, and switch to a higher level DoW/DoM class to clear the area around a node.

Anything more extreme, where the current system is more than just inconvenient, is what I'm trying to think of. Like something in a group setting.
