Looking for some info, gonna be partying with a Gunslinger

As to the title, I've gotten my friend to join me and he wants to go Gunslinger. What's the best (or at least decent) companion for them to travel with? 

I've always been partial to the type of play that Star Gladiators have with it being more active in watching, but I've also been looking at Ninjas. I don't have much coin for gear and it's going to be strictly PvM with the Gunslinger and my character. Would it be easier to party with them as a normal Transcendent-able class? I figured it'd be fun both playing as Extended classes.

Edit to add: I'm playing on RO Transcendence, not Renewal.

Yeah, I realized that after I posted this.   

So, I guess this would be more for when they do come out.

Unfortunately, even in the korean version of zero gunslingers haven't been released, or even if they have they haven't bothered to fix the broken mess of a class.

If they had I'd be playing one.

Class is the redheaded stepchild nobody in gravity loves sadly.
