Dragoon here, WTF do I do?

DRG have solid burst, actually.

The trick to playing large-scale PvP as a melee is to hit-and-run. Take a few hits, run out before it gets bad. Repeat. Your goal is to either finish kills for enemies already at lowered health, interrupt casters, or pressure enemies that have other allies already hitting them. All without dying.

That's the life of a melee in Frontlines.

My advice to you is: don't overextend yourself. Leap into the fray (possibly literally), do what you can, and get out before you die. Most of your time should be spent heading to and retreating from tactical hits. Do your damnedest to never die unless you secure at least 1 kill in the process. Ultimately, it's more beneficial to stay alive and try again than to push to the last of your life.

Also, for quick escapes, Elusive Jump is your friend and can really help put some distance between you and the fray in a pinch.
