Cap IW duped vs unawakened
I just got my first excellent 6* (cap IW).  However, i have a 5* r5 sig 200.  I'm wondering if i should r2 the 6* or not.  
I know his sig ability, so it's not that, but i want an r2 6* badly.  I'm not in a hurry either way, but i was wondering if anyone has an opinion one way or the other.
