Street Fighte V patch notes, at least for me, are very nebulous, there are dozens changes to each character, buffing and nerfing another dozen moves which makes knowing who is top or bottom in the end very nebulous.
After a big patch like that, the famed "tier lists" which suggest who are the best and worst character to pick are adjusted, but many times people will just parrot what a experienced pro player says or plays.
Personally, I find fun to give my 2 cents on the whole tier thing. Videogame isn't nuclear physics or ethics debates so it's okay to throw a (sometimes uniformed) opinion. It's nice to see your predictions are correct and if you are wrong you just switch mains and say you played Zangief since Street Fighter II.
