Great video, thanks for sharing! A couple things I'll note:

The pre-game battle waggle is absolutely necessary for success. It also instills fear into the bots of the other teams that you know what you're doing and are going to punch some faces in.

In your early chase scene, after the kill you're supposed to say WORTH IT! And then you say, "Okay so actually don't do that."

This is a great combat guide for Dragoon. You keep good positioning and use your maneuverability quite well. In that vacuum, this is excellent advice. The only thing combat related I'd like to see in a video like this is an explanation of the core of a Dragoon's burst. Even though it's "dumbed down" PvP, Dragoon manages to retain quite a level of complexity in the interaction between jumps and Eye of the Dragon and Geirskogul/Nastrond. I think it would behoove someone trying to learn Dragoon to understand that jumps give eye stacks and Geirskogul and Nastrond go back and forth, and Nastrond is a Dragoon's strongest single attack - so combining it with their other instants is a great way to burst someone down. Now in Frontlines, most of the time, you're playing a positioning dance which is crucial as a melee, and most of the time you aren't going to be getting off those burst combos except on ice. Which brings me to my next point:

In Frontlines, a Dragoon offers incredible, sustained damage on ice. Melee should really focus on getting ice points whenever convenient. Standing in the middle of three teams fighting it out is actually very hard for a melee to be successful in, and often times a melee's greatest contribution to the team is in racking up ice points. Since ice have magic resist, the magic based jobs should focus on zoning out enemies and getting picks or sleeping opponents damage dealers, clearing the way for melee to safely hammer on ice.

Overall, a great video on Dragoon combat techniques for Frontlines.
