I found at G12 he just gets stunned and dies so fast. Against meta, thrawn always fractures him, then cls does his second ability and he dies. I also found Biggs alone can solo him and shut him down. I had multiple matches where these 2 went back and forth until kru was dead and Biggs full health. Kru had 100% counter with taunt, Biggs gains 100% tm after surviving a critical so shoots kru, who counters, Biggs survives a critical and gains 100% tm. Had it happen 4 sepadate times and Biggs just shut him down, so I started avoiding those teams if possible. His basic did no damage to biggs.
