Lol I've actually really enjoyed Questmode. ( even though It's determined to give me pattern points for everyone but Lisa ) I'm so close to having all the challenges completed too!

I am too but it's upsetting since I haven't even unlocked Kasumi's costumes yet xD I want to give up but I keep getting hope but it gets destroyed every time I see who I really got a item for >.>

Yeah there really should be an option to set priority for the character that points go to, Or just let us pick the exact outfit we want to spend points on.

Or make them all buyable from the start with in game money but just make the prices at least 10,000 or something xD they could keep the pattern system in tho so if you do want to unlock costumes rather than buy them you'll have that option too

On the bright side, every time you get a costume for a character you don't play, the odds of getting a Kasumi costume next time naturally increases.
