The problem I think is that the gameplay will turn out to be fairly one dimensional. There seems to be only one real style of play, and that is using guns with some Logos action in the mix. Games like WoW, LotRO, and the like have a number of classes which allow a player to mix it up. Mages can be Frost, Fire or Arcane. There are Tanks, Rogues, Hunters with lots of variations. Tabula Rasa does allow specialisation of your character into a Guardian, Ranger, Demolitionist, Medic and the like later in the game, so itís hard to say for certainty on this, but Iím not sure it will really make all that much of difference to mix up the gameplay.
