Why are summoners so neglected?

So you mean to tell me that a summoner cannot use their aether for a burst attack rather than consistent summon is dangerous and a big no no yet a ninja and their mudra magic can do it all willy nilly just cuz they can?

Crystal summoning yes that is confirmed to hell and back in lore as bad. The summoner's current method is arcanima which is mathmatic symbol summoning which is not bad. They can easily write the lore that summoners trade a persistent entity for a strong burst attack without killing themselves.

You're comparing a split second summoning to do 1 attack to a job which is capable of keeping a pet out for an indefinite period of time and attack with them.

Actually let me add to that, if you haven't done the lv 50 NIN job quest, or was it 45, can't recall, but spoiler, we do see aspects of "Summoning jutsu" being performed by the antagonist which causes them to summon voidsent to attack us. So the lore has been there since they were released in the 2.X series to have some form of summoning.

Im comparing a summoning attack to a job that summons an auto attack. Which is the key issue since we didnt get summoner in the fashion of: Summon this big creature to do an attack because it was "too hard" along with other excuses and then they proceed to give a non summoner job that very type of attack.

What we could have had:
Summon garuda- wind elemental attack that deals damage and applies bio
Summon ifrit- fire elemental attack that deals damage and reduces damage dealt
Summon titan- earth elemental attack that deals damage and reduces defense

Or even if they were bent on keeping a persistent summon we could have carbuncle at all times but reduce its potency and have summons I listed and more as traditional call in summons.

With one move ninja performed a more classic summoning that summoner itself cant do.
