I try and limit every 5* as costumes are sure to come and, if it's new to me, it must be good as there are so many I don't have. What I don't like about a vanilla 5* is that if I 2 lb and emblem to 25, when a costume comes, I lose the ability to reemblem for the costume and not lose the 50 master emblems used to take the hero to 25. Personally, I hadn't been 2lb most 5* so I had plenty. Season of love though changed that as I received three of the top four and they became 2lb. As always, it's never a waste of it fits your current situation. A bird in the hand is worth two in the bush. Why wait for a better hero that may take forever to come?
