I see attack speed chain combos being perfectly mixed in the Dragoon style. The X>X>Z and X>X>X>X>Z are useful stuns that work well with the skills and stuns they have.
It's not like Overlord however where you need 300% atkspd and a good PC to make it work. Even with little to no atkspd bonuses you can make it work on a Dragoon if you aren't lagging.
This is from a PvP viewpoint however. It's like Overlord, where it's great to mix it with skills to extend and add hits to the combo. But not something you dedicate vital gear stats towards.
