I'll Take You All On (10 player)

Both of these adds are encountered by the raid group that goes through the gauntlet. As a result, it would seem this achievement is earned by all raid members that are not in the arena group.

Many reports are available of the entire raid or a large portion of the arena group getting this achievement. As a result, is does not seem to be hard to acquire this achievement.

I got this achievement healing in the Arena part, so it seems that everyone gets it.

I am surprised no one has mentioned this but the line "I'll take you all on!" is frequently yelled by NPC marine's in the game Halo (the first one) which was on Xbox. This is funny because they are often quickly killed by the enemy Covenant forces.

I am sure someone will point out that it isn't a reference and that the saying comes from many places. This is true but I still think it is a bit more than a coincedence. ;)
