I think the support class/tag should be renamed to distinguish between class and the role
It's not that I think "Support" doesn't fit as a description, but rather that it's a little messy that support is both a role and a class at the moment. A class is meant to be part of a champion's identity, and since Zyra, Leona or others tend to be confused for being supports (because they are or were mostly played in the role of the supporter) I think it may be better to rename the class Sona, Lulu, etc. sit in. If I remember correctly the term Marksman was for the differentiation of role (adc) versus identity as well.
Thoughts?
