Come on FFG!
K2 had at least about 30 mins of screen time, numerous lines, flew a U wing (saving everyone's a$$) and then sacrificed himself to buy some time for Jyn to steal the plans to the DS.
But we have Boshek who had about 2 seconds of screen time, no lines and a post-hoc EU background- like a certain toilet seat flying toilet paper headed bounty hunter).
Give us our heroes!!
