my previous comment was mainly that on the start of the event, already reaching 1.4 million is practically impossible within few hours. please perblue take a look on this. and by now nearing the end this is one if the easiest event compared to the others before (and i do sleep my 6 hours as usual, i know some people who wake up every 2 hours to do this) especially if u are already high level and you can deploy more missions. so far max missions can be deployed are 8 missions. i can do 8 on second day event and it helps so much thanks to buzz and woody friendship (the 8th mission i unlocked).
for you who hasnt reached 1 mil there are still a bit of time. perhaps this can help.
8 missions deployed:
a. hellen elastigirl and jack jack
b. mr.incredible and frozone
c. ralph and violet
d. dash and vannelope
e. yax and nick
f. judy and finnick
g. felix and calhoun
h. woody and buzz
someone has posted similar list above anyway. but zurg and rex is not doable now for server 2-8.
there are other combinations. for example if you use ralph and vannelope, then dash can go with yax and violet can go with calhoun and all mixed to get 8 missions with different combination. but sorry i’m too lazy to list them all possible combinations.
good luck
