KGB said: Retiring older 5* does the following:3) Helps those who fail to champ one of the latest before they leave due to bad RNG. Especially if they retire quite a few (like say 20 or so) old characters making it so there are only about 30 5* in classics. Not a giant odds improvement but it would at least be some improvement.4) No more dreading a new 5* release store / limited store when you see it contains a Civil War Cap or a FatPin. This recently happened to me a couple of stores ago when I was looking to finish Thor and I drew like 8 Civil War Iron Man covers so that I ended up champing a useless 5* I never wanted.KGB
