Yeah...but if PR wants to get rid of all the generic minor heroes and go for named ones...he'll need stats and backstory on quite a few people.
There is quite abit about Thrawn before the Thrawn Trilogy set during 0ABY to 4ABY, his promotion from Vice Admiral after defeating Zaarin etc. he has enough history, ships under his command and battles to be included IMO.
True enough, I'm just voicing my opinion of how Thrawn should stay in the game and how he has history beyond the Thrawn trilogy of novels that takes place during PR's timeline.
Also, I'm not sure if you could class his command aboard the Springhawk as relevant as it was before the Empire even began and (to my knowledge) we know next to nothing about Chiss ships or tactics. That said, how he suss'ed out that trade fed droid fighters use a certain code to attack was brilliant and should be taken into account if PR does a ranking system.
Incase anyone was wondering, yes I am a BIG Thrawn fan.
