I believe MOP cm Gold Sets should be given to all classes not just class wide for that one class. most arguments for against are just atrociously horrible as the CMs were easy to do I did them on my hunter as it was the only character I had max at the time I played casually in MOP and still do now. I have yet to see a logical reason for why they shouldn't be account wide as they can implement a system like they did for WoD, as well as they made the phoenix mounts account wide otherwise I would of had to do 4x 9/9 runs for each mount. peoples arguments include you should of had each class to max ( I don't have the time to play that much nor would I want to max each class as that is a learning process for each one), re colors/textures from legion ( not the same thing ) , the fallacy that everyone has the time to max every single class fully get it to BIS for CMs for at the time which was just socketed gear mainly ( again relates to the first point ). I have not seen a good logical reason for why they shouldn't do it they're unique yes but if I did them on one class does it honestly matter if I have them unlocked for all my classes because who ( casual players ) that did the Cms was going to run it one on each toon get BIS gear to clear golds logically speaking.
If you have a reason why MOP gold sets should not be added for all classes if you did them once state below. otherwise don't come at me with illogical rabble or strawmen as I will just break them down or ignore them entirely.
