This one makes me think all those nice fan-made maneuver dial reference guides are no longer legal:
Players cannot take notes or reference outside material or information during a tournament round. However, players may reference official rule documents or game components that do not contain hidden information at any time or ask a judge for clarification from official rule documents. Official rule documents include all rules documents available on the X-Wing page of our website, those found in an X-Wing product, or any portion thereof.
And they seem to have addressed the intentional draw issue with a "Mutual Destruction" option which leads to a "Final Salvo":
Edited by DailyRichFinal Salvo
If both players have the same score at the end of a game, they must fire a Final Salvo to determine the winner. To fire a Final Salvo, each player adds together the printed, unmodified primary weapon value of his or her remaining, undestroyed ships and rolls attack dice equal to that number. The player who rolls the highest total number of combined hits and critical hits wins the game. If both players roll an equal number hits and critical hits, they roll again until a winner is determined. If a game ends in mutual destruction, each player adds together the printed, unmodified primary weapon value of all ships in his or her squad.
