Necromancer Job Suggestion

[Enkidoh]

Wouldn't fit. Necromancy is a hanging crime in all of Eorzea. Caught with it, you die. The WoL doesn't make a habit of committing what is seen as capitol crimes. Even black magic is only illegal in Gridania and we have significant reasons to get away with that, there is no defense for corpsemongering.

Not just Gridania, it's a crime everywhere in Eorzea (especially Ul'dah, which, kind of created their own zombie apocalypse via alchemy centuries before during their war with Sil'dih and have since swept it under the rug, and have made great pains to keep it that way, so a Job that reminds everyone of that fact would not sit well with them at all). Also, and this is a very important point to remember, throughout much of the game's story the player's character the Warrior of Light has spent a good deal of their time outright stopping people mucking around with necromancy and other similar void magic, the game makes great pains to state within the lore "this is WRONG" and those doing so are criminals. So the WoL will never be one themselves.

And ignore the claims SE have hinted at the Job in the Heroes' Gauntlet; the 'Spectral Necromancer' in that is actually meant to be a reference to Lenna's Necromancer appearence from the GBA version of FFV - the other two bosses are similar references (the 'Spectral Berserker' is one of the Onion Knights as Berserker from FFIII, and the 'Spectral Thief' is none other than Locke from FFVI).

And just like why ROG was not called 'Thief' here in FFXIV, as Yoshi felt being a thief would not fit the image of the WoL, an outcast mage raising the dead as thralls simply goes against everything the WoL stands for here (even other 'dark' Jobs in this game really aren't if you actually look at them - BLM merely piggybacks on THM, and DRK is actually drawing on emotions, both good and bad, and are not actually evil at all). Necromancer simply does not fit.

And the final nail in the coffin (pun intended) to the OP: your idea is a pet Job, and Yoshi has stated how much he dislikes pet Jobs as they are extremely difficult to balance and take up extra development time to work out, so you simply will not see any more pet Jobs in the game I'm sorry to say (ACN's Carbuncles, SMN's egi/demi summons, SCH's faeries and MCH's turrets will be the limit of that).
