The Pirate "Hero" Class is Probably a Gun-user

Where's the facking gun?
That's a knuckle there is no visble gun

I don't think that image isn't meant to be speculated into much depth, and merely just cool concept art to show the Aran and their polearm. Nothing says they can't be Brawlers, regular Archmages, Bowmasters, and Shadowers, or its possible that Nexon didn't think that far into the future to plan what all the Hero classes would be like in the end.

We've even seen a whole thread about speculating on this, and we don't think there's any real significance to it.
