I just want to point out that the class uniqueness and superb utilization of the current classes dont stand out only because there are no in game contents to push players to further "strategize" their skill set (abilities) when they play any of the existing classes...I mean for example...an archer is a very deadly dd class atm if you know how to combine/use abilities with other dd classes such as marauder and lancer but at this time..what's the point? I can only think of trying to apply this concept on solo grinding so that I can maximize my sp gain/hr but other than that I don't see any other reason.

Again Kurokikaze provided a really good post but it would only work if there is in game content that would push this idea to its true potential. I would say that SE needs to provide us (the players) more challenging in game content to enable us to push on trying to come up with different ideas on how to fully utilize the classes before diving on trying to get the class modifications...
