As we all know, BG's will give you artifact experience, making them the least effort for obtaining experience for your artifact, and something botters will benefit from greatly.
I feel that botting will be 10000x worse than we've ever experienced or seen before in WOW.
Hopefully Blizzard cracks down on botters? I doubt it, though.
Really going to suck PVPing in Legion now that random BG's are more rewarding than they've ever been before
I really don't look forward to it.
