Short answer: The Worf Effect. It was a big problem under AEG and you can probably expect to see a lot of it under FFG as well. It's just the nature of L5R, when the whole setting is organized into groups who are good at "thing"s, then you can expect to see every time in the fictions that when someone or something shows up who is also supposed to be good at "thing" then the fact will be displayed by them one upping someone from the group that is supposed to be good at "thing". The Crab will always be overrun, the Scorpion will always be outwitted, the Crane will always be outmaneuvered, the Lion will always be defeated, the Phoenix will always be corrupted, the Unicorn will always be... out... horsed?, the Dragon will be out fortune-cookied, and the imperials will always look bad at doing everything imperials are supposed to do. Because otherwise no antagonist will actually look like threats.
