OK lets take all the things asked as a rework or to be removed for reasons
Arcanist line up
Egis
Dots
Difficulty
More demis
1 animation hit summons
Lets talk about the easy one first since it encompasses 2 more.
the Arcanist line up that supposedely makes no sense to be tied to summoner and has no interaction with summoner. for this ofc ill take the 4.1 summoner because its the car before the devs carcrashed it. first of all Arcanist isnt Just the dots he is aetherflow ruin summon 1 and 2. obviously if you rework it till its unrecognisable that means jackshit but, you cant do any trance / demi without going through an aetherflow rotation. not only that the spells you get from summoner, unless they get the bane treatment, also need it. Also even if it is upgraded ruin is still a spell from the arcanist and it even gets further upgraded by Pet actions and trance. The dots Also gets upgraded and trance rewards you with a free ogcd refresh which combined with aetherflows flexibilty allows you to have an easier time refreshing the dots. The pets themselves need no explanation they dmg, they buff. they need fixing so that we dont have 2 and titan.maybe they Will at some point if theyre alowed to.
Difficulty
we're literally the mage Who has to do calculations to cast his spells and Who has to beware of his weakest points in order to achieve his highs otherwise rip demi summoning
Demi summons
We Will get more demis that was the whole point of stormblood We dont need to make the egi demis when We can fix them to make them feel as good and maybe better.
1 animation hit summons
Those aren't summons those are just attacks with the animation of a summon . if fester does 300 potency and a summon comes does 300 potency and then leaves for like 30 seconds that isn't a summon it's just a fancy attack it's the rdm sword attacks . sure you can make the argument the unbalanced pets are glorified dots even though they can at least buff you (devotion) but they aren't shallow you have to deal with them . honestly the 4.1 summons were better than they are now especially cause of little neat tricks like misaligning the garuda cooldowns so that she casts without delay contagion and you didn't need to cast ogcd for them to move.in that aspect my question is why ask for 1 strike abilities when they can put that effort into designing the next demi summon or even our first elder summon.
Story wise Summoner also makes sense . and even though the summoner quest line isn't the most intriguing compared to dark knight the back story of summoner and the connection it has with the Ascians it's the best piece of lore in the game cause it's heavily tied to the main story. off you can say i don't care about story . but if the story makes sense , the gameplay made sense and after they tried reworking it to get a bigger audience it doesn't make sense , why would you push for more nonsense to the point of reworking it unless you really dislike the job . do you want the title of summoner so much that youd rather destroy it and build it into your own image than asking for another job. if this isn't the summoner you wanted ok but this is summoner and many people like it if you don't like it Don't play it . we shouldn't be forced to get a rework every expansion just cause summoner isn't to everyones liking especially when they hit the spot already.
