(Waiting for Rook to get back off the floor)
I have Skittle @1^1. My othr greens are Elkanen 2^40, LJ 3^60, Mel 3^60, Kashhrek 3^11 & Caedmon 3^10. There are two more of both LJ and Mel plus Brienne way back.
Since I am way past 30 heroes, is there any reason other than hoarding to keep the ugly green fella.
And, in a more general way, is there a single reason 4* s are untouchable. Arguing for one hero like Wu won’t work here.
