Lack of character "skills" customization...?

[Fire-Dragon-DoL]

Because in a FF game a Summoner is a Summoner through and through - Throughout the series they either had access to White Magic or Black Magic but the main thing they always had in common is that they summon pets. As much as certain people hate to hear this, like Kiria, but having iconic jobs like this completely customizable throws out the whole purpose of them making this a FF game, they should drop the Final Fantasy title.

For example a summoner that focuses on their pet while another that focuses on debuffing more doesn't fully make sense - It should be more Summoner A focuses on using x summon(s) while Summoner B focuses more on y summon(s). The problem is unlike XI they went with a limit choice in skills since even though you "outgrew" skills in XI you had many more options. You simply will want to wait for more jobs to release that specializes in X.

I would LOVE to see a summoner specialized in usage of different summons but actually there isn't anything like this, that would be ok (and doesn't differ at all from speccing, I don't specify you MUST do in a specific way, I'm ok with this idea).
While I like your statement really much (I love the fact that classes have a huge background because it's an FF game), I feel being trolled: I've chosen summoner because I imagined it integrates a lot with background thanks to how summons behave, the truth is that my pet is just another debuff so my "summoner", become easily a terrible WARLOCK from another well known game (and I really hate warlock).

Not to mention the fact that you have more or less 0 interaction with your summon... The scholar has much more interaction with his own pet (yea, the fairie!) than the summoner.
Why there isn't something like 10 spells on my summon (obviously reduce summoner spells amount) and something like GAMBITS to manage your summon?

In final fantasy, summons were huge (now they are really small) beasts which when summoned, had a long animation, and usually destroy everything.
In final fantasy x, yuna was useful with her healing spells, but when she summon something, you see that she's one of the greatest character in the game.

Here, I'm a beastmaster, not a summoner. Well, beastmaster loves more their pet, my pet is just a debuff.
