Summoner is currently my favorite job. I like the difficulty of it, and how it has Raise and a good party damage buff and how it still does great DPS, nearly as much as BLM and SAM, at the cost of this difficulty of dealing with finnicky pets and having to make sure your pet abilities have gone off so you don't ghost them and making sure you don't move too much so your pets get all their attacks off.
I also like how pets can currently damage things while out of range for mechanics (such as Ancient Flare in Labyrinth).
While new SMN looks cool, and maybe I'll enjoy it, if the damage is compareable to BLM people are going to (rightfully) complain and get it nerfed since it can't be easy to play, high damage, and have a rez for balance reasons. I'm going to want my old difficult to master good at everything 5.1 Summoner back.
4.2 Monk also had this going on. In 4.2-4.4 it was very high skill with double-TK and also strong.
Now Monk looks to be made easier than ever to play. But also probably will still be "worse Samurai".
Don't get me wrong, I think it's great that Square is making jobs feel better to play with combo buttons in PvE bringing the number of buttons you have to press to around 20 for most jobs, and making a easier skill floor for most jobs so it's difficult to perform badly.
I think new Summoner looks cool and I'm glad many players like it more than the current Summoner that they find too difficult. But if it's... basically a reskinned RDM, I doubt I'm going to care to play it.
The problem is: there are still those of us who like a job that is difficult to play and master, and it feels like Square is completely ignoring those and completely doing away with that with each expac.
I guess one solution would be to give us alternate job stones to change spec or to make it so Pugilist and Arcanist get the old Monk and Summoner designs (with 70-90 skills added).
I understand this isn't really elegant, but might be worthwhile instead of a new job.
Square could instead design a new job that, instead of what they said about Reaper "We think it'll be popular so we designed it to be easy", they could say with this new job "we wanted to give something to people who enjoyed the difficult 4.2 Monk and/or 5.1 Summoner play style".
I'd personally like a magical DPS melee with a rez that can do "selfis DPS" levels of damage despite having a rez and raid buff, but is mechanically difficult in how you line up your rotation even if not necessarily positionally heavy to actually do that damage.
Even if players who want this "difficult to play and master, but rewarding" job like 4.2 Monk and 5.1 Summoner was are a minority... that minority are still players of the game and shouldn't be ignored.
Making a job for them does not hurt the other players who enjoy these more streamlined and easy to play job reworks. 2% of players wanting something like this is still tens of thousands of players.
