5 frost DK?

I have been thinking about how to get around the waeknesses of 5 boxing mellee and it seems like 5 frost dks properly specced and macrod might have a chance. Round robin deathgrip followed by x4 icytouch and 1chains of ice seems like it would solve the closing and positioning problem. You wouldnt need to hold them long because x5 froststriked would finish the job. As frost you could spec lichborne and still spec into blood for runetap and conbined with unbreakable armor, icebound fortitude, and antimagic shell you could buy enough time to survive the aoe/cc barrage. The kicker for me is round robin hungering cold. Hungering cold is awesome and the ability to repeatedly cast this after the opponent trinkets out would be priceless. Anyone else have any experience with a setup like this? I initially was thinking unholy or blood for multiboxing but the more I think about it you need to really spec to minimize your weaknesses and a frost spec seems like it could get around alot of the issues mellee have in arenas.

It has potential to stomp a good chunk of the teams out there, but when you get past 1600 rating it'll be really tough without a healer even with team healing rune taps. I play melee in arenas and one of the biggest problems is how easily a blessing of protection can ruin your burst - and they always know who you are trying to kill because you are melee and have to have your victim targeted.

Hungering cold with 10 diseases on each target just eating away at them for 10 or 5 seconds would be devastating though - when it worked.

Ya melee teams are not so good in pvp boxed. If the person you are chasing goes immune (iceblock, BoP, etc) you now have to acquire a new target and get to them. This is precious wasted seconds and usually means someone in your team is dead already. I just dont see this going anywhere.

It would be pretty killer in battlegrounds.
In arena, you'd get pts each week, but probably not be competitive at the higher ratings.
