I have a 3*, will be 4* with daily shards. I have his passive and his basic at level 3, but i havent shifted to leveling yet so he is only lvl 43. In GW i bring him in if i have any trouble. He is always my first (and usually only) replace.
Even at level 43, this guy is a body dropper. Im excited, and anxious, to get him 4* in the last week of December, level him up then, and see how he does behind my 6*, tier VII, level 59 Stormtrooper Han.
