to be fair, this contest ends on 25.10 and dating tokens expire on 27.10 so if you get the 10 shards on 25th or 26th you can spend dating tokens to get the remaining 90 shards
that is still a big IF:
- if you get the 10 shards on 25th or 26th
- if you have enough dating tokens
then again, almost every player is missing so many girls it won't be easy to pick just 1 of them so it seems like a drop in the see as we're over 900 girls total to acquire
and the elements update will be out when the contest ends
i guess, unless you have a girl that is missing 10 shards or less to be yours, a reasonable idea is to pick 5-star legendary with an element you have the most/least of and compensate the rest with dating tokens
