What if the new agent(probably deadeye) won't even be one of the 4 current classes(duelist, initiator, controller, sentinel). Because Riot said that there will be probably like 12 classes and like 5 agents in each. So it should happen soon because there are already 5 duelists, 4 initiators, 4 controllers, and 3 sentinels. Which means at least within the next 4 acts. There will have to be a new class. Unless they changed their mind and will have more than 5 per class.
