After having completed this fight, I have to say this is a fight in sunwell where a prot paladin is very viable as the MT over a warrior. The boss itself doesn't hit TOO hard that only a warrior would be able to tank it. Here are some advantages for us prot paladins in this fight for you guys that will be attempting felmyst soon. Maybe this thread will help you be an MT for the progression fight
1.) Felmyst is an undead, so a fully T6 geared paladin's threat will be much higher on this fight compard to a warrior. Higher threat really helps for this encounter since aggro DOES NOT reset between phase transitions. So if one of your ranged DPS gets too high in threat in phase 2 Felmyst will go directly on to them which can get nasty since he has a pretty wide cleave.
2.) Bringing a prot paladin for this fight for phase2 is practically a must since it makes that phase EXTREMELY easy than having no prot paladins. Holy paladins can yea pop RF and conc to pick up a few but at max maybe 4 or 5 they hit clothies for about 1200-1500 and holy paladins for about 700-800 I believe. There is a LOT of adds by the end of the beams before the breaths come in so yea this phase is much much easier having an aoe tank to grab the skeles.
3.) Another reason why we're very viable for MT is that avoidance isn't as big an issue as threat and effective health on this fight, which makes us almost on par with having a warrior MT. A lot of the damage the MT takes is from his aura which ticks every 2-3 second for 1000, corrosion which he casts every 15-20 seconds, and a dispellable vapor gas which actually should get max one tick off. His melee swings doesn't hit too hard.
4.) Having a paladin tank MT gives you flexibility on that open raid spot where we were the OT since we can tank both phases without a problem you can add in to the raid what your guild needs most to progress. For example if your phase2 is not too clean and the skeles are not getting picked up fast enough before breaths hit then maybe you want to bring a druid OT in to dps during phase1 and help grab some adds you couldn't get to with also bringing in another battle rez. Battle rezs help in this fight a lot although we only used one resto druid. If your having problems getting past phase1 due to dispels not getting off fast enough or healing you could free up that extra tank spot with another CoH spec'd priest. If your lacking in dps, bring in another ranged dps.
I won't go into too much detail about strategies to use and what the best ways to pick up the adds in phase2 so you guys can go find out for yourself. But for all the paladins who have felt that blizzard hasn't given us any content where we shine over the other tanking classes, well here it is imo.
I encourage all you other prot paladins to talk to your guild about taking up the progression MT role for this encounter. If there's anything in TBC for paladins to shine as a MT, I believe it's this fight. I mean they even made corrosion non spell reflectable
