There are 4 Specialization types in game. Each have their own default abilities, purchasable active abilities, purchasable passive abilities and gear item set up for PvP. This allows each specialization to fill a specific role in the game. To make a great alliance you will need multiples of the specializations and their different skill progressions.
A player can choose any of the 4 specializations at any time by going into the “Agency Specialization” from the Alliance menu. This will give you access to their skills/abilities, however you can only use the skills/abilities of the specialization you are currently using.
