People will get over it, or rather people should just move on. What's done is done and Frost got punished for it, even if the severity of the punishment wasn't enough for many people but Riot made their decision and continually talking about it won't change nor make the situation better, for now.
In any case Frost just played better than everyone they've faced so far, even TSM admitted that they played better than them.
