What is this going to accomplish?
People already complain that summoner is just an arcanist with fester. Removing the Scholar job from arcanist is NOT going to fix summoners. The issues with 'how a summoner feels' is much deeper than the job that also branches from the base class.
First of all, we have what is essentially death magic (poison and disease) coupled with elemental based pets. It's like taking an elementalist class from any other game (or even blm) and slapping it together with a warlock or necromancer but then doing nothing to try and fuse them together so it makes sense, but that is what it is. It's not going to change. Moving on.
Second summoners aren't just basically arcanists with fester. The job gets spur and enkindle too! Oh and of course tri-disaster which is a disaster of a spell. (the ratio of potency to mp plus the time it takes away from your regular priority/rotation makes it a detriment)
The problem I see with the job is that it never really gets anything of it's own.
There's the extra summon spell, but it's summoner so I'd think having more things to summon would be a given. Plus consider that summon and the trouble it can get you into with certain encounters and you'll see some of it's steam taken away real fast.
Tri-disaster is essentially a much weaker long range version of blizzard 2, and save for a couple of rare instances is not worth casting period.
Spur and enkindle are 'ok' they're not really job defining and enkindle on it's long ass CD isn't exceedingly useful. It's certainly not as useful as say fester is.
Fester is really all summoners have that is a constant variable in how the job is played. But really when you think about it, fester is just a continuation of the base class's playstyle. So except for essentially 2 minor spells and one useless one, nothing really changes between arcanist and summoner. So I kind of have to ask.. why even have summoner? Why not just give fester to arcanists and call it a job?
Look at scholar and how drastically it changes, Adloquim, Succor, Leeches, Sacred soil and Lustrate. Of course they're all healing oriented spells and of course that'll change how the job is played. But notice how lustrate and sacred soil operate off of aether flow stacks. Summoners get one extra spell that works with this mechanic, fester. Why couldn't something be tied into aether flow for the egi? A decent increase to spur perhaps and something flashy while spending a stack?
But it's not just scholars vs. summoners on their post job abilities that are defining characteristics. Dragoons get their jumps which are varying degrees of useful (granted SE dropped the ball on damage negation or even reduction when using them but.. ) blms get more defining spells, as do monks, bards, ect... Hell Blms get freeze which is a big increase to blizzard 2, summoners get tri-disaster? A weaker version of a level 12 spell at... level 40... :-|
So where are the spells that define summoners?
Also aside from the horrid graphics of the egi. (Which by the way you can't tell me their graphics were lowered to reduce distractions or for any sort of hardware capabilities, that's bullshit. Look at carbuncle, look at fairies. Both have nicely detailed models and good texturing and they work just fine. I'm not saying we need a titan or garuda as big as the primals themselves, that would be stupid, but some more detail or better models wouldn't be impossible now would it?) Anyway aside from the graphic hideousness. There's very little interaction with the egi after they're summoned. Sure you should cast spur, rouse, enkindle but its never anything more than just hitting off gcd buffs just like every other class does, which aren't taking up two of their job specified abilities.
So maybe instead of saying "Oh this class needs to just be completely remade" (because that is not going to happen at this point), or "Summoners should be split from this or scholars split from that (which won't fix anything.) Try thinking of smaller things that could be done to spruce the job up. Maybe shift its focus a little more from dot dot dot to pet pet pet. Or maybe replace or rework some of the more useless spells, tridisaster would be a good place to start. How about arguing for an extra spell to make up for the one that is lost for Summon III (summoning spells shouldn't count, it's a summoner job. Plus scholar pets don't count against their 5 job abilities between 30 and 50)
