These titles were designed to be difficult- but not impossible to obtain. The Specialist title was only awarded to the top ranking Crafters and Gatherers for each day of the event. The Rebellious title was only granted if your damage killed one of our Developers. With this being the case, if one of the Developers managed to fully heal before being killed (and you not damaging them afterwards) then this would negate you getting the title. If you believe that you should have received one of these titles, you can contact our Community team (Community@RIFTgame.com) to further review your eligibility.
If however, you are missing one of your Ram, Raven, or Lion titles please contact our Customer Support Team to review your request.
