Only thing I don't like about this suggestion for a skill line is how specific it is. Playing a dragon knight would be cool, but that's the type of thing that you would build your whole charecter around. So for instance, if I wanted to be a death knight of sorts, I would just mix warfare with necromancy and bam I'm a death knight now. So for a dragon knight, I'd probably be an inquisitor with a focus on int and constitution, taking warfare for to be in the fight as well as pyro and focus more on tankyness and fire damage. Grab pheonix dive with the warfare skills that get converted to magic damage with a staff, then grab fire spells.

So I can think of a pretty workable dragon knightish build right now, so just imagine what we could do in the full release with all the spells. All we need is an armor mod to change your armor to some badass dragon armor and then we are even more set.
