i want to play online games with other players, how can i do

we all know how the most broken character can break even the AI and make it give up but what about the weakest one? so far i only played the 4 main characters: i beated normal mode with Reimu and Marisa first try, Ran can easily melt boss attacks in seconds but then I don't know what to think about Sanae: in term of attack he has mildly annoying extra and boss cards to face against (at least in normal mode), but in term of defense she's pretty lame: no bullet clear move, and both regular and charged fire ...

LETS WALK FORWARD TOWARDS THE FUTURE OF TODAY WITH OUR HEADS HELD UP HIGH FOR WE WILL EAT FEAST AND DINE AS OUR ONE AND ONLY MIMA WITH HER UNFINISHED DREAM OF ALL LIVING GHOST WILL RETURN TONIGHT

Failed Failed Failed Connected but 3fps, opponent left midgame Failed Failed Connected and above 30fps for half of the match, desync victory, end match dialogue needs 10 minutes to display Failed Crashed

I have cleared all the main characters(the ones with blue background) and started playing with Aun all of this in hard. I haven't seen a match where i have lowered a boss 1 or 2 hearts, i always finish the match from full life to defeating the boss, i am thinking all of this is tied to time. What do you think, do you feel AI in story mode is pretty scripted?...
