Pretty much this.
I'll be the first to admit the new system isn't perfect, it's far from it, like several other features in the game. But the way to 'fix' that isn't by removing everything that was added, but to look at what was added, and see what could be made better.
A thread like this isn't a solution to a problem, as it would only make things worse, since you would remove any chance of improving that Minecraft has by removing features that can or do work well.
Thank you. Take it from a person who loved the old PVP, and quit because it is gone, this is the best thing to do. This new system needs to be revamped a little as well. MC doesn't work if you remove every new update that a minority doesn't agree with.
