These are awesome. I really like them. But as always I do have some feedback for them. Thou not as much as always.
Boss Nass:
Like the idea. Only problem I have is his unique Proud Ruler. It isn't really clear to me how to upgrade it's level. How do you get the 8 different levels on this ability?
Jar Jar Binks:
This is my favorite kit of them all. It is beyond clever. Remember A while back when I said that you made the best kit "for now". Looks like I was fully right :) . Only thing that bothers me is the Critical Chance down on his basic. He also has a taunt on his special so that really feels worded weirdly. It feels like it belongs in a unique more than on his basic. With the way it's worded at least.
Captain Tarpals:
While I get why you did it, his on death bonuses are weird. He isn't the tank in this team so he won't be targeted. And seeing how his unique allows for more booma's to be placed you kinda don't want him to die either. Maybe grant the entire team bonuses whenever any Gungan ally dies? Would make more sense from a game play standpoint. Or make him an off tank in some way. You do have 3 supports and 3 leaders in this team, which is a bit much.
General Ceel:
I only think the on death bonuses from his leadership are a bit weak. You lose an ally for crying out loud. You are allowed to do some better things.
Gungan Soldier:
1 problem: the bonus action from his unique. If you mean this like raid bosses do than I'm going to say no. That really is a raid specific mechanic that falls really flat when you consider player control. I really advise against it. Instead I have 2 different solutions. Both already existing currently in the game. Either make him attack again, using his basic (like darth revan using lacerate under certain conditions) or, my personal preferred one, have him have a chance to gain a bonus turn. Like Wicket has. Those would work and be pretty neat to have.
Booma Debuff:
The damage on placing is too high. seriously, you are supposed to place this all over the place yet it does 20% health damage? That is way too much. I recommend reducing it to 10%. Also, considering they reduce speed I think they need some sort of max cap. maybe 10? Seems fair.
Overall these are awesome. Great work as always.
