Apologies for the late reply!
First things first. I love the concept, and it has great potential to fuel long-term rivalries with monks that could persist all the way down to the EoL of WoW!
Unfortunately, however, your character’s background suggests that he learned from pandaren monks, but never studied under a pandaren school, let alone a master who chose to carry a pandaren’s teachings onward. We (including I, really) understand that this condition sounds convoluted and extremely limiting, but we believe it’s crucial for an event made to honor the teachings of Kang, and many other schools that followed in his footsteps, that these same teachings are indeed represented - and indeed honored.
We (again, including I) understand that this is frustrating as the Celestial Fist Tournament is the only unarmed tournament, and monk-centered tournament, and martial arts tournament that roleplayers have to flock to, but despite critique that we are already way too lax in whom we allow to participate (yes, really - that is a recurring critique), we work hard every tournament to give and maintain the Celestial Fist Tournament the identity it deserves.
That is not to say there is no room for revenge stories. There absolutely is. Rivalries between pandaren schools can be an extremely elegant point of entry for hatred and vendetta.
Having said all that, there is still hope. Valladia is currently organizing a Grand World Tournament (May 27th - 30th), which will be featuring single combat duels on the fourth day for monks to partake in as well!
I hope this message has cleared up any confusion on how we strive to decide on who is and who isn’t qualified for the tournament.
