As we know, There are some argues, as if Samurai should be tank or DPS.
Well, first of all, we don't know, if it comes in next expansion at all, but hype is strong enough to say that it would be cool, if it was considered.

As to say, we didn't get any Arcanist-like splitting proffesions.
Regardless, if Samurai will be implemented, or not, adding more shared-weapon jobs with different roles could save some concept-making time, maybe even balance up to level 30, or simply pleasure of gaming with certain weapon as different role.

And when we mentioned level 30.
Next classes starting from level one? Please?
Beginnings are funniest! Don't take them from us!
