I just had a thought for Atamos in CT, and I'm wondering if anyone has tried it or has any opinions on it.
In a melee heavy party, rather than having a tank pull awkwardly all the way back to the platform, then leave it quickly for the next pull, or do a tank swap pulling to the platform, have a healer pull.
A healer and a tank stand at 6 o'clock on the platform, the others on the platform stand at 9-10 or 2-3 o'clock to avoid dragon tail swipe. The pulling healer at 6 o'clock casts a physick/cure at an add spawn, or keeps regen on someone. This should be enough to take over threat and pull the add. The tank takes over with a shield lob/tomahawk, if there's a whm he can use holy as the add arrives, and the people on the sides wait until the mob is in position to start their attacks.
This isn't something to try in a PUG, but a FC party that doesn't have 2 ranged dps might be able to pull it off.
