And hundreds of thousands of people more are looking forward to a Summoner that doesn't hurt people's hands to play and that actually focuses on summon magic after 8 years of waiting. The abilities your buttons change into are varied enough, it's already been demonstrated that we get to use a higher number of different abilities mapped to these buttons while still having good flow.
I'm ready to buy multiple boosts of Summoner for my alts and countless new players will be drawn to this class, and current Machinist too which for whatever reason these players who are apparently far more skilled than the ordinary player seem to dislike with a passion. Regardless, beyond their echo chamber the masses are still cheering for this rework just as they did for when Machinist received the one it got for Shadowbringers. No amount of complaining will dampen that excitement, nor will it force the devs to revert these changes and create yet another new job next expansion like they've had to do for Summoner each time.
