5 mages

[beeq]

If I remember right, the pumpkin soldiers act exactly like mirror images.
(summoned with The Horseman's Baleful Blade)

I don't have those blades atm, but I think the mighty Faxmonkey demonstrated it on one of his "Stupid mage tricks"-videos.
If the pumpkins wipe your threat while they are up, then it opens doors for other dps classes as well.
(also awesome when you can switch weapons in mid-fight, so when images fade, drop your soldiers to keep aggro for another 30? seconds ^^)

The reason why I think 5 oomkins would not work is the fact that after the pull the boss is already on one of your toon's skin. Also I can't imagine even epic-geared boomkins do the similar dps than an arcanemage is capable of.
(dunno how treants threat work tbh)

Thumbs up Multibocks! My experiences on setup of five mages have been awesome, and still is! My other 5 mages are now 81, and starting to 10man stuff in near future, old content 10hc/25man stuff so let's see what adventures that small army can still achieve!
Btw, I just leveled alchemy for guild cauldrons. Much cheaper to spend 4 flasks and some stuff on a cauldron, than drinking 10 flasks each hour. Especially when guild cauldron flasks last 2 hours, on an alchemist 4 hours
