Just wanted to point out this part of the translation of the Famitsu interview done by Reinhart:
Famitsu -
You said armory system will be used in future but we worry that some class balance is bad and will not be used. We’ve seen comments such as maybe its better to get away from armory system. Please explain the plans for job system and armory system.

Yoshida –
I believe there should be action/abilities which only those class people should be able to use. We call it class identity. Think of it as a trait you can show off to other classes. Currently there are no limitations to switching actions and no matter what class you play the end (setup) isn’t much different. Would like to make it into an armory system it should have been where classes like Gladiator can perform more tank and Marauders being able to do bigger damage/critical damage.
So at least we know that SE intends for Marauders to be a big DPS class.
