So far I'm pretty well on track for 20000. It's a 12-day event and I've managed about 2000 points per day, which should keep me on track. I haven't hit Vegas yet, though (should be there by the end of the day), so I don't know if that will change my odds or anything. (I don't know how the matches will change, if at all, or if the stamina cost of jobs will get a reset or continue to rise.)
So far so good, though. I didn't understand how to claim tokens before, nor did I know that if you did earn tokens that you got extra points as well. It's really helpful to take a stab at matches that other users are doing so that you get extra points and tokens, but the problem is that they're not always available. And I don't always have the stamina to jump into finding my own opponent. Even if I do, it's likely no one else will attack them with me, so I usually miss out on the bonus points there.
By the way, I'm unverified. I have an army of costume Rares and some event Normals. Moderate power, but I wish I could claim some of the SRares I've gotten from other events.
