Savior atma...yeah, I wish. For those who don't have it, would you just go RR/DG/MC?
I gather from that post that there's no "trick" to avoiding/mitigating Disgorge? You just eat it and call a new pet. What if he does it again before CB timer is up? There are agressive mobs all around the area ppl normally fight him at, so should I be pulling him far away to somewhere where I can safely kite until CB is back up, or maybe just try not to feed any TP until CB is up?
Mounted Champion is fine instead of savior. Several other options would work as well.
Disgorge does not always kill your pet, but is the only thing that is likely to. You do not need to swap pets often. Maybe 3 times if you drag it on forever. I never had to kite waiting for CB.
Savior atma is like anything in abyssea, its not really hard to get, just takes a little time and focused effort.
