There have been beyond numerous posts regarding people who want to have another way to obtain the Mists of Pandaria Challenge Mode Gear and the reason is simple: it’s basically, by far and away, the best transmog gear in the game. I agree with not allowing it to be obtainable again, as that how limited-time stuff should be.
However, there wouldn’t be such a large demand for the return of MoP challenge mode gear if Blizzard would create new sets for each expansion for each class to obtain.
I am here just asking Blizzard to please put more thought into their creation of gear sets for new expansions. I mean, classes no longer even have distinct tier sets or even pvp sets.
Transmog is important to alot of people with the toons that they play; it is important to me. I do not feel incentivized to play other toons. I have challenge mode gear on my druid, shaman and paladin. I adore these sets and, as a result, I find myself continuing to main these classes even though I feel as though I would like to try tanking on a DK or healing on a priest.
I think it wouldn’t be too much to ask for blizzard to release challenge-mode type gear for each class for each expansion as well as bringing back the Elite PvP sets for each season. It would make people feel more excited about learning to play new classes with an important goal in mind to earn.
