Qi'ra: All around balance leader and of course the only leader ability within' the current Solo movie characters. Do not underestimate the Unique zeta, btw.
L3-37: I have not zeta'd her yet, but yeah... even at G11 she is in the top of conversations of taunting tanks in the game.
Young Lando: really great basic attack, a special that grants stealth, and another special that has ability block and reduces cool downs, and one of the only 2 characters that can give target Prepared.... again, in the conversation for top kit in the game.
Young Han: A special that stacks himself +200 speed with retribution and protection up, another that can recover an ally's protection, also can give a target ally Prepared, and a unique that stacks offense and CC while assisting.
Vandor Chewy: Another bad-a tank that recovers health and protection for himself and ally's while forcing opponents to attack him. A revive is always great and with the two "Young Toons" able to give prepared to who they want, the ability to revive can almost always be there.
Left out Nest and Range cuz they are just pretty great... as you say.
