Instead of possible builds being locked behind faction grind and therefore not available to new players, they should get Prisms for saving the world trees as they unlock the map.
Sure, put prisms with perks at faction vendors, but having the hybrid ones locked behind the different faction only makes changing up your build as a new player way more difficult.
Too many new players I have talked to get frustrated cause they cannot change their build fast enough if they don't like what they originally chose.
