Why are people setting this up like the only options are dumbed down lobotomized baboon rotation with summons vs. complex rotation without summons?

There's literally nothing about the big summons that requires having a brain dead rotation. "It feels like a summoner now" is not in any way, shape, or form a counter argument to people complaining about the simplicity of it.

"Not every DPS needs to be complex." Ok, well, not every DPS needs to be simplistic either, which is what all 3 caster DPS are right now. Red mage somehow coming out in Endwalker as the most complex of the casters is weird considering it's intended purpose was to be the easier caster. That's where we are right now, if you want to play a caster your most complex choice is red mage.
