Gunslinger comes out on the 9th?

I don't understand what you mean. The landscape changes to Iria, the Raid System, Explore Uncap to 30, Tara changes, and etc existed on a Thursday which was before Episode 1 launched. White Dragon Raid and the Shapeshifting forms existed on a Wednesday before Episode 4 launched.

“	if	„

Small word, large significance.

Not to mention, doubtful. If anything, it'll be similar to how fighter and puppetry skills were released: with a so-called "sidequest". And if it is, then op would be correct.

Besides, all those changes were small changes that had little to nothing to even do with the storyline (other than b/w dragon raid). On the other hand, dual gun is an entire talent class, weapon set, and skillset. I'm doubtful it'll just appear out of nowhere.

Sidenote: are guns even sold by any NPCs?

The Zeder Gun is sold in the mines and by a new NPC near every trade post. The rest are all from Engineering with the exception of Golden Dowra and Black Star which were from G18 in KR, a gachapon for JP, and unknown for NA.

You were able to obtain the skills immediately on implantation in KR and JP.

You mean through that Talent Beginner Quest or?

I meant you could obtain as soon as it came out in the maint through normal methods.

• A: Get the first skill, rank it up, get two more, rank up one of those two new ones, get two more, etc.
• B: Do a series of tutorial quests if you RBed into the correct talent.
