We already know that Destiny will have 4 different types of damage: Kinetic (which is the basic one), Solar, Arc and Void. Also, everyone who played the beta should have noticed that there was a 3rd empty subclass slot. Due to the facts that The Warlocks Voidwalker is based on Void damage The Warlocks Sunsinger is based on Solar damage The Hunters Gunslinger is based on Solar damage The Hunters Bladedancer is based on Arc damage The Titans Striker is based on Arc damage The Titans Defender is based on Void damage I assume that the Warlocks/Hunters/Titans 3rd subclass will be based on Arc/Void/Solar damage so regardless of what class you have chosen you can deal any damage by selecting the particular subclass. Do you agree?
