Yes thats why i made this post, info that you can find there is just not really accurate or detailed enough. Also the attribute part on that page just shows your base attribute which can get increased by promoting level 20 char back to level 1 so yeah not really that much useful...
I don't believe there is a stat screen explicitly because scaling is different in MP compared to SP. I think they figured people would be confused or complain, as they are oft to do, so kept everything in the backend and stuck with the old school street fighter style strength bars on character select.
This would only make sense if attributes made 0 impact on your character stats in sense that every character have set values but this is not true. In fact MP part works exactly the same as SP part ( - some extra buggy skills) except that instead of 3 different classes you have 12 different presets where skills are often mixed.
Hell there are even some passive skills that directly boost just your attributes and nothing else so yeah...
I can only hope then, that they will add such thing in future and tbh this feels more like oversight which was made simply because of lack of time or proper testing.
