I'm not sure why MCH is considered unforgiving now with the shorter wildfire. Trying to get decent damage with the larger wildfire was a lot harder, and you still had to cram a ton of stuff into it. MCH was the least played job in HW.

I think the job changes were needed, because a lot of jobs really were a pain to play well. I don't see people here complaining about how much they missed having to constantly refresh multiple DoTs with every single job, or how much of your DPS was due to that. I don't really miss how many buffs most classes needed to use in their burst and how much latency could hurt then because you could have so many you had to double weave. I think they had to do it if just because the rotation holds back how hard they can make encounters. Now that the skill floor is raised, they can make difficulty stem more from encounter actions and less from players screwing up their rotations.
