What I really wish they did and which will never happen, is just make 1 Data center for PVP.

So if you wanted to PVP you would just have to travel to that Data Center. That would solve so many queue pops problems and increase the player pool. Then you could remove the Frontlines XP and potentially have enough players queuing up.

But nothing will happen because the games are pretty much always pretty decent on JP data centers, so we are stuck with the XP farmers.
