Yep this still works and you are correct in that it works from LK raids and up.

I have done Firelands for this whole expansion and have also got saves for Ultraxion and Deathwing.

I had a save for Throne of the four winds also but just recently got that mount to drop.

As for the saved toon setup i have all my lock-outs on one toon apart from a double lockout like Dragon Soul.

I dont want to tell you my kill count for Alysrazor in Firelands lol, i just ticked over the 420 kills and still no mount.

There is a few runs to do each week so its something to do iin the end of this xpac.

Lich King Heroic can be soloed by a fair few classes now. Just check out youtube for class specific strats.

As for Yogg i havent dont much of this at all so best to look at youtube but i have a 5 box hunter in guild that does it easy each week i think he has his pets do most of it while his toons face away from yogg so insanity dosent stack on them.

Throne of the four winds boss is pretty simple but to make the air phase easier id take a few DPS in each kill , pop cooldowns and just go nuts.

Firelands - Alysrazor takes i think 200k dps to kill which is not too bad for a geared player, just dont go too far away from the boss in the air phase or he resets. Remember to go through every fire ring in the air to get the haste buff + you need it to stay flying.

- Ragnoros : Im not sure how many can do this i bring in 4 ele shaman and a guildy on his lock also comes in.

Dragon Soul - Ulraxion : Just spank him blow all cooldowns at the start and go nuts, with the 4 ele and lock combo hes dead before hero ends.

Deathwing : 4 ele and lock in there also , quite an easy fight at 90 we just save cooldowns for the last phase and the totems heal us enough to stay alive .

i think thats all i do each week.

Im sitting on 233 mounts at the moment but they are getting harder to come by now lol . I also do the world bosses on 12 toons with an alliance raid once a week and was lucky enough to get Sha's mount the other day.
