I changed my stance on this several times as people debate 1-2-3 will be boring or just not practical to merge when only a few jobs dont have divergent rotations GNB DRK and MCH being the only DPS with a never ending 1-2-3.

For the people against it:
besides MCH, no job is just its rotation DRG need its disembowel and jumps NIN needs its ninjitsu, SAM never had a straight forward 1-2-3. MNK also need to focus on keeping up twin and demo, no caster needs this besides of few QOL stuff like RDM physical finisher and SMN Trances and some tweaks with BLM. The job wont be any easier , a case here and there can be made with a few tanks and MCH but otherwise the jobs will retain their joy and make room for other refinements and free up space
