I personally would hope they would at least activate the materia slots in pvp with the pvp materia, if they would bring in IV or higher of the existing one, I wouldn't mind.
If you have full 205 gear, why the hell you get synced down to 150, that is crap. The argument with new players doesn't count in my opinion, they have to swallow the bitter pill at the beginning, but there is a goal for them to achieve while pvping.
In the current state as it is, what use has pvp gear really? moral doesn't work, materia slots are inactive, and the thing with the synced down... why even bring in PvP gear then?
I had hope, they would maybe activate all of this when the season starts, but I got dissapointed, maybe they will change this, because I don't see a reason why people that play more should not have an advantage to those who don't.
