Dunno if anyone has mentioned it yet but lots of people are overlooking a key factor to Marauder play, AoE.

If Mrd did the same single target dps as Archer or Lancer then the class would be called Archer or Lancer. Marauders are the masters of AoE threat generation and do great AoE damage. Before NMs were *cough* nerfed into the ground, Marauders could easily generate 1k+ tp with a single broad swing and spam his AoE weapon skills without worry.

Mosshorn fights as Marauder were incredibly fun since those adds have a decent amount of health. Marauder's TP generation on those fights were unmatched even against a pierce + invigorate II lancer.

Point is Marauders do have a role in a party, the real problem is there is no content at the moment that can bring out a Marauder's full potential.
