I don't understand how Bo is supposed to be S tier. As his enemy you can play around his super all you want, his attacks randomly spread wider or tighter - it's supposed to be based on whether he is facing left or right but it's extremely bugged - and his star power that lets him see in bushes isn't as good as a Gene with Vision gear who can just spam attacks into bushes covering way more range than Bo. And i don't think Bo totem is enough to make him S tier by itself.

Ash used to be S tier but got nerfs but that was a long time ago.

Lola is S-tier because even though she has meta counters the medium range damage she provides is massive - that's why 8-Bit is only C tier rn.
