First of all, sorry for my english, i hope you will understand me without too much effort.
I have some characters on Frostwolf, i like MoP pvp, and I would like to play quality pvp on Forstwolf. It's true that Frostwolf has between 300 -600 people, but it's obvious that the activity of this realm is not enought for pvp. You can try if you want, and you can also see the armory. You will easily see that 2s and 3s arena are not active, and that pvp is poor. Pvp needs more people, and the fact that there are 600 people dont means the pvp of this realm is not dead. If people can't play normally the game, i think mods should do something to try to improve the realm of frostwolf, or maybe let it die and offert some solutions to people.
I apologize one more time for my bad level of english, and thank you for reading.
