I prepared this easy table to show that it would be best to keep shards and not pull during the current x2 Void weekend event.
As noted, in the past Plarium never offered Void Legendary champions during Guaranteed Champion events. But this changed in April when they offered Riho Bonespear for 90 Void Shards. This means it might happen again.
Then it would be better to gather shards for that because that event would yield expected value of 1.4 legendary voids versus only 0.9 of the Void x2 event.
