This thread at this moment is the equivalent to me making a thread saying DRG does too much damage and should be nerfed. The problem with this is I do not know how much damage DRG does because I have not seen or played DRG in the 2.0 version. Just like how the OP said that classes are bad. Yeah they were pretty bad in 1.0, but abilities and traits are going to be changed in 2.0 to accommodate for the new battle system. As already stated in this thread, before an overhaul should even be considered we should see how classes play out in 2.0.
Jobs were and always are meant to excel in each respective role while being restricted in other aspects. The concept of a class is to have more customization for solo play.
