you got to understand, as a game dev they want more ppl to play the game for the games health/population.

battle design are evolving. what use to be more stationary now evolved to more movement. like every expansion since sb, blm while remained same rotation, new spells/abilites were added to provide some sort of mobile. for was it shb or ew where ppl start saying blm has even better mobility than rdm restrictive dualcast.

as combat/battle evolve, so are many jobs will eventually too. as much as i do want to get back the old hw/sb kinda gameplay, it pretty hard for the general playerbase to wrap their head around that kind of skill rotation.

while making the job easier wont improve your gameplay experience, it will incentive new player to try it out.

having a job that has high skill cieling would mean theres a big disparity between a vet and a new blm (or any other job) player.
when theres disparity, it will feed into meta and dps balancing for fights. you will see jobs gets bar from joining x fight.

thus why the dev have to maintain a healthy job balance to enable every job are viable for x fight. which some what relate to the game population health.

sadly of course no all changes are well thought out. looking at 7.0 launch blm and similar case in the past for other jobs that gets rework/change shortly.
