Pugilist seems like a good DD to me, and with flurry he has a pretty awesome speed, i dont think lancer beats us single target.
I think pugilist should have better damage on single target mobs than they do now, especially with the game probably shifting focus to party vs party. then the advantage of marauder and lancer is really going to grow.
Pug should be able to shift from heavy DD to Strong tank, versus a single monster, much like their original plan, the pugilist should be the class that can go heavy attack, and have more options for doing that, or heavy defense and have more options.
light strike/ with on evade skills and heavy with flurry are the start of this, but it needs more, maybe some more offensive combos, like skills that can only follow a flurry, or a critical hit, for large damage. Defensively, maybe some more buffs that work from the light flurry buff, or things that increase stats, or something on evasion.
