Before I start, I just want to point out this isn't a complaint but more a curiosity.

So in Heavensward, Dragoons receive 'Fang and Claw' (56) and 'Wheeling Thrust' (58). What I don't understand is: other than the positional requirement (in terms if you want to deal higher damage) it's exactly the same skill... My question is why?

Is this to purely test skill cap of the player or perhaps there's some hidden mechanic I'm not comprehending?
