Just curious if I'm in the minority or if this is typical - I have a decent bunch of 5 star characters, mostly 4 star characters, slowly converting my 1-3s up to 4/5.
My "A-Team" all have 5 star talismans and I'm at the point of wanting to explore what all my other characters can do.
In order to get these other characters to fight at a comparable level, they'll obviously need 5 star talismans as well.
But after a few weeks of just farming the highest levels I'm getting tons of colored runes, and extremely few rainbow runes. Is this a common bottleneck?
