I never normally bother with these events. But this time I did purely because Special Sponsor points were available at the start. I stuck with it to the end and finished second only because there was one team of mutants above me.
Very time consuming you are right. I was lucky with my draw as I was the second highest rated team at 122%. Nice to get some tokens but not really worth the time every two hours.
I think there needs to be some more attractive prizes in the future. Maybe phased prizes at the end of each day such as those seen in Special Sponsor.
