Optimum signature level (5* champ)
I saw a post long time ago discussing the optimum level of signature level for some champs. At that moment they used 5* Hyperion as example and said that ~50 sig stones are good enough (his sig ability at 73% something) as there is diminishing return in applying additional stones........etc.
Is that comment still applicable nowadays? Any other example of champ(s) who still have optimum sig lvl I/O max out? Thanks.
