Exactly what I want to know aswell. Some are generally way more difficult than others from the mechanical point of view (Tugar vs Kruul), and some are just tuned insanely difficult (Agatha vs Closing the eye for example).
I would love to see the participation / success rates for specs aswell. Although I completed 7/7 challenges and even some duplicates on other classes to get the mogs, I still feel some are severely overtuned if you compare them to others. I would welcome nerfs to some without a doubt. Right now, MT is done and dusted for me, but if we would see some nerfs, I would attempt 12/12 classes, maybe even 36/36 in the future, but right now, it’s way out of reach for me since I’m not so good at certain specs.
For example, fire mage, elemental shaman, WW monk, fury warrior are very easy in my eyes. Way too easy if you ask me. I would compare these challenges to early 7.3.5.
The middle ground would be frost mage, retri paladin, VDH. These are fine if you ask me, and felt like very early 7.2.5. or even 7.1.5. I like this difficulty, and that’s how the majority should be if you ask me.
Others I completed, were insane. The Xylem one for havoc is insanely tuned. I barely completed while maining a DH since day 1 it was introduced. I would really like to see the success rate for this. Also seeing (didn’t try these) affliction warlock, shadow priest, boomkin ones, holy priestI don’t know, they feel way too difficult, I would never attempt these. These must have incredible bad statistic numbers.
Healer one is also very brutal if you ask me. And it’s not the same difficulty as Kruul which can be abit harder due to bad RNG, bad luck with orb spawns, lasers etc. Healer one is very linear and ‘programmed’, meaning everything is always the same. But if you miss 1 thing, it’s a wipe. I did it on my shaman and druid, and it was incredibly difficult. P1 was insane on shaman (absolute perfect play needed to beat it), and last phases were very difficult on druid.
The most interesting one I would like to see is the Kruul one for guardian druids. The success rate / attempt rate must be crazy here
I have the felbear myself (obtained after 30 attempts), but I know people have some insane attempts on this.
