1 reason i prefer Lancer to PUG / Marauder and other dps classes, is i found that our Stun is much quicker than other classes, we have higher survive-ability
than other dps classes, i leveled a Lancer to 20 and a Pug to 20 in phase 4, and found pug was much faster and had more options ability wise available
but i still prefer Lancer, not needing to mess around with stances or moving as much, once your get Full Thrust it really comes together also.

Cant wait to try out Dragoon, the jumps look to add alot of interesting aspects to the class. Also i think Lancer has more HP and Defence than other DPS
classes, during phase 3 our little group did not have a tank, so i tanked as lancer, all dungeons up to 35, we not much difficulty, i know we're a DPS class but
being able to take some hits, helps.
