Raid Guild Challenge... with 5?

Theory Craft:

I'm just curious.

Is it possible to accomplish the Guild Raid Challenge (defeat a raid boss at appropriate level) 5 boxing?

Like, Karazhan at level 70 - 5 boxing, but with WoTLK Greens, or WotLK raid boss with only 5 with Cata greens, etc?

Any loop holes?

My lonely guild could use the guild experience :(

My guess is that you wouldn't even be able to get the credit without 8/10... but was just curious. I'd level a team purely for this.

Completed Molten Core with a 5-man team. Did not get credit for the guild.

Time to find another multiboxer on your server to join your guild. Two 5-man teams could probably come up with something.

you need minimum 8man raid to complete guild raid challenges.

Nah it has to be 8 regardless.

And if you have one toon that is over the level req it won't count.
