You misunderstand.
My point is that if there's a significant DPS difference between "barely doing the rotation" and "doing the rotation optimally", that's going to cause problems for Jobs that don't have red icons. The only way to have "more damage buttons" and "a more interesting damage rotation" THAT IS FRIENDLY TO CASUALS - the supposed reason we should add more damage buttons instead of upping the healing requirement - is if the DPS gap for dropping those extra buttons is negligible. Otherwise, you aren't doing it for the casuals, you're doing it for the hardcores to chad on the casuals.
Which is fine, if that's the argument you'd want to have. My issue is more people being...less than honest...about their intents.
Or, maybe, they genuinely do believe that it would be easier for casuals to juggle 3 DoTs with different timers and keep near 100% upkeep on them than to have fights where they have to press Medica 2 four times a minute and a Cure 2 or Regen in there to taste. I can't imagine HOW anyone would believe that, but maybe some people do...
EDIT:
Oh yeah, totally agreed. There needs to be something.
Unfortunately, that ONLY works for procs. DoTs are still something impossible to make easy to track unless they completely redo the way enemy bars are displayed, especially for multi-target fights. Maybe have that "SCH shield breaking" sound effect or something when one falls off...something like that would at least alert to "Oh yeah, check your DoTs."
