The new gear will make a lot of people new to PvP at least try it out. Once they start realizing how long the grind to Rank 40 is tho, they'll surely stop it as fast again.
The system that SE has in place to currently seperate different ranks from playing with each other didn't seem very effective the past weeks but then again that might have been due to the amount of people actually queueing lol
Effectively it will just be more meat for the meat grinder of R30s getting to R40 tho

Kinda sad since PvP in this game is so much fun once you get into it.
Not on a base level of "I want gear handed to me and just zerg the enemy camp with my 20 over-geared buddies" style but in the style of actually having to put thought and preperation into your strategy/kill order/gear and materia choices/PvP point distribution.
