If you tie the Wyvern directly to the Dragoon in terms of attack times, etc. Then there's no point of having the Wyvern there for anything than aesthetic reasons. And, as I said before that's absolutely pointless. Why would we even want something like that as it adds zero game-play value?

If you create wyvern specific moves from the dragoon, then you're essentially taking away from the dragoon's moveset itself. (If you're going to tie it directly to the Dragoon's motions, a Dragoon might as well just be doing it itself, it ceases to have any context of a pet class and you're just making more work for the animation department.)

I don't know, some of these half-baked ideas are really coming from left field here. You've gone from "Oh We're going to take 10% of a Dragoon's damage and tack it on a pet" to "We want a graphical extension of Dragoon."

It's horribly demeaning to the concept of both Dragoon and Wyvern.
