I'm confused about nute being labelled the worst character in many peoples opinions....because from what ive seen...he has some pretty good abilites...
My Nute is lvl 48 with VI gear
First, he goes insta stealth-mode pretty consistently, and when upgraded his basic attack to lvl4 he hits just as hard as characters like Luke or sidious.(both are lvl 54 atm gear VI)
Second, he gains defence automatically for living allies..
Third, he gets major critical attack boots while in stealth..
Forth, if you decide to use his "special" which is a bomb that has some stupid 3 turn delay trigger, IF it goes off on a character your not focusing on, like barriss.. or chewie.. it attacks the whole team pretty nice.. (mostly for PVE)
