Entering v1 solo is indefensible and you cannot explain otherwise. Your doing everyone, INCLUDING YOURSELF, a major injustice by tying up the queue lines, and also you're giving up a huge chunk of gallantry which is not insignificant. Normally people who solo for a seal is very minimal in damage, but if you truly insist on soloing, why not just team up with 2 other soloers and make a lowman out of it? It's much better for everyone involved.
And some of those soloers have tried to join parties, but they ran into *** who insisted upon RMEA for friggin N'runs.
Or were told that they can't go on X job, because people want BP:Rage *** bandwagon SMN who forget that you can use Ward too. God forbid Asura players actually try something different. Almost every shout is for SMN, Idris GEO, or RMEA BRD. That's extremely narrow for casual/newer players, and the sheer rudeness of some players can intimidate someone who's just trying to get gear (because gearchecks to get midrange gear make SO much sense).
'Course, that person can always pay for a few VD clears.... ohwait no they can't because they're poor.

Can confirm that damage is low if melees stop swinging after Boil message. The tank can poke at it or supports cast Dia repeatedly.
We had a SAM solo the pony.
The Meeble Warbles deal almost no damage.
Don't attack the dullahan (WS it? Not sure) while pony is nearby and alive; its Scintillant Lance oneshot the entire party out of nowhere, dealing about 7k to everyone. There was no multiple uses of Lance; it zapped the hell out of us.
Dullahan is incredibly susceptible to enfeebling magic, with the exception of Distract III, Blind II, and Dispel. I landed Distract III several times but was unable to Dispel it, using belle helene/resistant cast set/Saboteur. Didn't try Stymie. Silence is helpful. It's immune to Gravity and Break.
I don't believe enfeebles cause escalation (Charge---->Boil------>Deathga) because I threw everything including the kitchen sink at it while our PLD kited it after a wipe.... it never Charged. I'll note that Paralyze might be counterproductive, as it won't gain TP to complete the escalation cycle if almost every action gets eaten by Para.
Dispel spamming the Pony, much like others of its kind, tends to force Grace of Hera. Too much TP feed strengthened its AoE, it seemed.
Light skillchains will stop Miasma if performed immediately after the message; if you wait too long it seemed ineffective. Within ten seconds after the Miasma message, maybe?
So- tank on the Dullahan till My Little Pony is dead, then cautiously DD. Skillchains not recommended except for Light to break Miasma. GEO used Fury/Frailty, and I main healed/enfeeble spammed on RDM/WHM. DDs were SAM WAR BLU.
