Any classes that give pets/minions?

Besides companions - Like droids,turrets, beasts etc.

Well not in form of passives/active skills.
Pets and minions are pretty much strict to Cartel Market items that you can redeem on your characters.
You can get them via Cartel Market purchase or from Player Market directly.

Those are just for cosmetics then?

[Taiga]

Yup, they're just a cosmetic follower.

The closest you'll come to non cosmetic pets are a few cartel market companions that are actual beasts, such as Nexu, Ginx, Akk Dog, Nathema Voreclaw, and a few others. They can use all 3 combat roles just like any other companion, and I believe have a few special interactions based on influence level.

You'll never have more than 1 'fighting' companion unless you so solo flashpoints and get that combat droid they give you to help you though the flashpoint.

As others have said, there are no summoner classes in SWTOR.

While you can have pets follow you around, it really isn't advisable... for one, they are pretty much a waste of money due to having zero use outside of just "being visible".

But more importantly, a number of Flashpoints, especially the vanilla ones, can regularly crap out if you have a pet spawned.

Last but not least, you need to respawn your pet manually after every planet to station, station to planet, ship to station, ship to planet, etc... just gets annoying real quick.
