Fully decked out players from Blackrock on Frostmourne.
This is literally unplayable to my standards, I am a new level 80 trying to gear up having to constantly battle fully decked out Blackrock players on the Frostmourne realm. If I wanted to push 2's / 3's etcetera etcetera I wouldn't be able to, my rating would be stagnant because of the constant outgearing from players who took 5 minutes to buy all of the pvp gear from a vendor.
Suggestion: Put a gearscore/Item level cap on players from other realms, that way you could specify example: 3k gearscore for Blackrock players if they wanted to play with people on Frostmourne, because as of current situation this won't be viable long term for the regular casual player trying to gear up on Frostmourne. Please Warmane!!
