Maybe I was dreaming but I seem to remember reading that Yoshida recognises the problems with pvp, like not being able to enter until you are at level cap, and he wants to address accessible in Stormblood series.

For what it's worth, Frontlines doesn't need certain party composition to enter, and starting next week it won't need GC composition either because we can fill spaces in other teams with the freelance option, so this will be a boost to cut wait times.
