well my FvS is usually more than welcomed in TOD, though to be fair I haven't run it for a bit... I guess it depends on the person playing it..
Reading the OP plus other responses, and really knowing nothing more than what is posted here,
all I can say is Two Healers on the Tank? What?
Obviously I do not know the skill level/experience of either FvS's, Tank or Party Leader. But in the case of the OP I believe they were all to hold some responsibility on this cluster...
1. Party leader for not setting up the healers to be successful in a high stress environment
2. FvS's for not coordinating with each other
3. Tank for not taking charge of the healing resources when they realized they were not getting the supplies they needed.
I would throw the customary blame on the Cleric, but none was mentioned. So if a cleric was not present than its their fault because they should have been on the ToD run. (hehehe)
The point of confusion: if they are not use to working in tandem they will second guess each other every hit, being more worried about wasting resources than keeping the tank alive.
(20-20 hindsight)
This could have been avoided with:
1. FvS 1 is the main healer until they use 50% of their SP
2. FvS 2 is the spot healer (watches party throws a few spot heals to the main tank as needed)
At 50% they switch roles. This right here allows for the "Backup healing", can prevent under-healing (first reason why tanks usually die) and over-healing (second reason why tanks usually die) [All other reasons why tanks usually die lie with the Tank]
As for the comment about droping "Those Two" and getting others and completing with no problem, hats off to the group, However, I believe the real reason for that completion was that the two "healing classes" picked up knew how to work together, had a better grasp on the situation or Someone actually took a leadership role.
The sad part about this is that the two people that needed to gain something out of this experience, probably never will.
The OP identified the class of the healers rather than just saying "Two Healers exclusively on the tod tank and he still died" which indicates to me the OP does actually think that the class played a role.
I don't know why this run failed. One thing I do know for sure. It is not because you had two favored souls instead of two clerics. Take the same players and give them all the same gear on clerics instead of FvS and you would get the same results.

qft and bolded for emphasis.
It sounds like a failure on the leaders part resulting in healers not doing their job right. Class is a moot point and has NOTHING to do with it...period.
A Horoth tank should NEVER be under 500hp IF AT ALL POSSIBLE....unless you have a backup tank to take aggro WHEN...not if...a 1 is rolled on Disintigrate. I personally have been hit for 520 on a failed roll and some have mentioned higher but I can't verify that. Any time your Horoth tank is close to that mark, you enter the 5% chance to die realm...doesn't matter how good you or anyone else is.
So, you chose to blame the healers. Narrow minded but I see your reasoning. Tank died, their fault, there were supposed to keep him alive.
I don't just give them a free pass BUT......you said you had to *remind* them to heal because, you saw your MT at about 50% health right? Did you at least *mention* that your tank WILL at some point take 500+ damage to the face?! The fact that heals came at @20% mark implies that your healers(again...class doesn't matter for squat)simply DID NOT KNOW THE MECHANICS/DETAILS OF THE ENCOUNTER!!! The failure is partly the leaders....and partly yours OP. You seem to be aware of the mechanics at least somewhat yet all you did was yell "HJEAL HIM!!!" from what I gathered. What if you had said..."Alternate Heal Scrolls or something-JUST DON'T LET HIM GET UNDER 500HP!!! IF HE'S AT 1/2 HEALTH HE CAN BE ONE-SHOTTED!!!"
Not everyone knows the raid(or any encounter) and most are too scared to say so. Too often newer players get kicked out for being honest and asking for help. Try being supportive and helpful, explain WHY's and everyone benefits. Judging from your OP though, I feel I can safely bet how those two players were treated afterwards....
