Also, they should alter it to show it to everybody who has that class leveled, instead of just show it for people who are currently using that class.

For example, I' m waiting someone to use party finder for titan EX so that I can join it with my main class as a healer, but then I got nothing to do on healer while I m waiting, so I decide to leveling on my sub-class while I m waiting. I will not be able to see any of those party finder that recruit white mage, but not recruiting the class I m currently leveling on the wait.
