If you continue to dumb down the game, you will lose half your player base

It depends on the player. I find it fun to press 500 different buttons during combat. Some don't, and that's okay. The real problem is drastic job changes. I agree with OP: "Dumbing down existing jobs is not in any way acceptable, and is an insult to players who main those jobs. If you want to make something simple, then you need to create new jobs that are simple from the beginning." Summoner was my first main as a Sprout but now I fall asleep when I play it.

Summoner's situation was given up on by enough people in 5.0 to warrant a rework that it should have received in Heavensward. There was no salvaging that mess, not with how much more prominent its glitches were and how far gone it was from the original focus of the class in the context of the Final Fantasy franchise as a whole.

There is no reason why as a level 90 summoner I have no access to Shiva/Ramuh/Levi. Get to work SE! By this point in FFXI I was walking around laying waste to everything with Fenrir and maxed out elemental summons I had gone the lengths to power up with the merits system.
