Since you gave no examples or any clear ones i cant really agree or disagree, this is the first time ive ever heard anyone call MCH challenging . Ive played HW and SB MCH and other jobs in varies expansions and MCH is the easiest job ive ever played to a insulting degree. MCH being a ranged too, meaning its easier to DPS, along with the least amount of skills in the game and lack of intuitive mechs is a huge anomaly and the reason the outcry is relevant. In the MMO market and for the devs being way to willing to trim mechanics and resources we dont need starter jobs, job that are designed no to be fun but to be accessible and safe. Risk and reward , one of the fundementals of game design waning due to no risk
Beauty of mmos, changes happen all the time and MCH isnt gonna change in a patch, and sadly wont change much in expansions due to the universal praise for its lobotomy
