So many things are said about PvP... Good, bad, etc.
My suggestion is such.
Leave it alone.
No nerfs, no changes, no nothing.
Leave it alone and never touch it again. Seriously.
It's fine how it is, out of the way and unobtrusive. I like it where it is. So do most people who love it and who hate it.
Leave PvP alone. And stop talking about it.
If you have a better suggestion, please voice it here.
