My teams are only mid 60's, but I love my DK team for pvp. I perform much better as my DK team then I do my shamans for AB. If this pattern is any indication of what they will play like at 80, I'm honestly more excited to get my DKs to 80 then my shams
I call my team The Ghoul Storm, and they have one main trick that I MAKES the team. It's glyphed Rune Tap. When they all rune tap at once, they heal themselves for 20%, and everyone else for 10%, so it's like a 50% instant health heal for everyone every 30 seconds for my team of 4.
Like i said, i have no experience at 80 what they will perform like against gear opponents, but right now they are SUPER fun. Also I leave my leader in Frost, so he has lots more HP and armor, as most people target him, and all the others in blood for the extra damage.
If anyone else has DK multibox info/tricks please post I would love to make my team even better!
