My game time runs out in a few hours so i probably wont be able to post again, unless something comes up will only sub when 9.2 comes out. if this post is able to help a single person i was already worth it.
will leave some of my alts links here (not all, just the ones with the easier challenge for mog) with the gear they did MT challenge with, most of them are not fully optimized because i was learning as i went taking notes of gear that worked and stats i stacked, talents, etc.
Sigryn - enhance shaman, ret paladin (both versa haste), demo lock (first time ever playing demo, haste crit)
recomended trinkets: seed pod, gaze of sethe, dragonling (make sure to stop sigryn cast before she gets the fathers buff, if u do u can break CC immediately and stack all 3 for cleave dmg, enh shaman was over by the 3min mark), this is where seed pod shines.
for ret pala i used a 2H heirloom with crusader i swaped around with warrior
Tugar/worm - WW monk (versa crit), seed pod alone kills the eggs, making the fight trivial unlike destro and BM
Xylem - arms warrior (crit haste), imo is easier than frost DK and DH, make sure to use interupt followed with spell reflect to heal up with second wind talent. below you can see i was sinking gold in pvp gear before i started to know the tricks above. friends i coached on budget gear did not need the pvp gear.
dragonspine from gruul is very impactfull here. i used a 2H heirloom with crusader for both arms and ret pala, i just swaped it around between chars
important: you can extend the P2 phase by leaving the first pool ontop of orb in center and then rushing to edge to leave second pool.
Kruul - bear druid because of felbear skin, tough challenge still (versa and haste/crit), but DH was by far easier (crit and more crit), took me 1 hour to do it, use spiritbomb heal on variss/kruul to agro the 4 adds to u (just saved u alot of frustration trying to figure this out like me). seed pod is godsent to aoe adds every second wave, make sure to use seed on bosses cleaving the adds

Twins - i leveled a mage with sole purpose of MT but after new year i was way to tired to focus properly, will try it next MT time. WAY easier than MM hunter or Boomie. being lvl52 is important for frost mage for the extra rain of ice dmg.
Agatha - i did this on my DK with his raiding SL gear, stacking as much mastery as possible. a more indepth guide below. friend who aplied the gearing method and followed tips below did it in less than 2 hours (and this is learning to play SL dk). fury warrior is easier (more mobility) + crusader enchant.
next MT ill try xylem as survival hunter, twins as frost mage, sygrin as rogue
healing challenge i never healed before, goodbye book mount
