Second biggest problem of snow ARURF after limited champion pool imo...

... is how we are forced into flash as a summoner spell. I get it why we are forced into snowball, because that's in the theme, but why only flash? Why can't I take ghost? Or smite? I won't talk about tp cause it's obvious why Riot would not like this summoner to be used. But what about the others? I think some characters like Singed or Voli would sometimes rather take Ghost over flash for example.
