Who is the worst character?

CLS.. He is not strong enough, well, yeah, he broke the game and he is able to kill a character in 2 or 3 hits, but, as a REBEL he must be able to ONE SHOT every character (as Wiggs, Chirrut's Strenght of Purpose, Raid Han does) l am so mad, l hope that CG fix this someday, Jedi Knight Luke should be able to kill a character with his bassic.
