dunno, if it was really as bad as you make it out to be the go to 4 warriors party wouldn't be able to do it so easily would they, they have no healing or esuna afterall?
They made up for the no-dodge roll by making his telegraphs like 5 times slower by the way

He's way easier than just about any other extreme trial btw...
probably even byakko

Inner Beast
Inner Release
8 hits of regain HP
Equilibrium
Storms Path
All first phase.
Second phase is really up to the user.
But yes, you can survive with a 4 WAR strategy, even without a healer present. You don't need to heal Esuna, since the burn is actually not as bad, even with 4 stacks.

I've run WAR WAR PLD DRK
WAR WAR WAR WAR
DRK DRK DRK DRK
And PLD PLD PLD PLD
I've also run it as a full DPS RDM party and Melee party.

Didn't have any issues whatsoever. Phase 1 is cheeseable with tank, and that's mostly because of the fact that Tanks can survive with no heals and no esuna. You don't necessarily need a PLD for any phase, but it's an extra added bonus. WAR WAR WAR PLD is the better of the strategy, only because the PLD can Hollowed Ground the Bull before the second phase. PLD or WAR in Tank stance can take the brunt of it, while 1 up top mounted and the others in DPS stance tanking. You also do not need to grab any adds except the Coeurl on phase 1 since everything else, Rathalos can actually kill with them being attacked constantly. Staying to the left of Rath's leg for most of phase 1 of the fight is the key to the fight. Also, avoiding his un-telegraphed fireball that he occasionally that he does, is about the most you need to watch out for. Otherwise, if he's facing you, that's you're que to pay attention and move. I do not raid with endgame content, but Monster hunter being one of my absolute favorite series, have taken a hand full (even more since I had to do 50 runs for the mount), of players, and turned them into hunters with some luck and some navigation of move sets. I've actually spoiled tanks the most since they prefer the run with tanks now, as opposed to dps and healers. Now, I will admit that the normal strategy with healer + tank and 2 dps may seem like a lot, but it's really not. You just need to have the HP to survive most of the move sets. Your party should have HP about 43k to survive most hits. This is from being one shotted by rathalos, should you not move in time. I advise everyone be at least 355 or 360+ for the VIT HP pool though.

During phase two, you have two options:
1) Stack together
or
2) Take your lumps (tanks only of course).
***********
Option 1 - Stack mechanic
Because you have 4 people stacking at once, you can reduce the amount of damage altogether. The group just needs to move as a pack is all and not shy away. If even 1 person decides to shy, you can instantly cart. This is assuming you're doing the traditional Tank Heal DPS DPS. If you're 4 tanks though, the damage is negligible. You can't even see it. Just need to prepare heals for the third hit.

Option 2 - Tank only single stack. I'll explain this one since it's a little longer than normal:
WAR players - With WAR's high HP pool in Defiance + Thrill of battle, you can actually pop those + defense CD > take the first hit > potion and take the next two. This reduces the amount of times you need to consider healing or popping a potion in that phase. By the first hit with Defiance and thrill of battle on, you should drop to about 20-30k hp. Use a potion here. Second potion, don't use till both hits have come through. If you're using defense CD's, you can easily survive with 99k HP and more. Depending on what your gear composition is at the time. I've never had to use more than 2 pots. This includes the burning tick after heal, which drops me down to about 66k hp, where deliverance would be about when in the stance. Between 60-68k hp. People say defiance doesn't matter, but I've run multiple tests on it and even with no HP regen on your tank in phase 2, you still get the additional DEF from Defiance stance + thrill of battle HP with a full heal at 95-99k hp, and can take 2 hits as opposed to one.

PLD - If you're a PLD, using Sheltron + CD can reduce the amount of times necessary to use pots during the phase. If you have a DRK, the DRK is popping TBN on you, with you running sheltron, the damage isn't more than about 30% hp. This includes the burning tick. You should only need to use maybe 2 potions at most. 3 if you get below 40kHP + burn tick of 3-4 stacks.

DRK - If you have a DRK, you can pop TBN + CD and survive without using pots the same. Even better if your PLD uses intervention on the player with the marker, and DRK pops TBN on top of that. Same with PLD strategy though.
**********
I've run it on DPS and Tanks strategy, with little to no deaths. A number of times 3 carts can happen. It's a monster hunter thing. But the overall strategy behind the non telegraphed fight, for most monster hunter players, (to some of us who have fought Rathalos in the games), it's not as bad as everyone is making it out to be. The only issue I've had with the fight, is that the gear itself, should've been monster hunter related. But this gear, while still cool looking, is better than anything they've had in stormblood so far. So I can't complain too much. Overall, a good fight for many monster hunter players, and mount achievers, with having the Rathalos mount.
