One of the ways we were supposed to get ascendance fodder was by ascending 4*, however we are not getting 4* at a fast enough rate for this to be a useful tool.
Let me be clear, WE DO NOT WANT 4* TOKENS OR PRESTIGE TOKENS AS TOURNAMENT REWARDS. That being said we need a better source of these tokens to aid in the ascendance process, maybe some hefty 2-8 hour scavenger missions that award 1k-2k tokens? Maybe a regular roadmap that awards large amounts?
This process is not ideal as it takes 3 million food and 400+ same persona survivors to fully level a 4* but many players like myself probably have a good stock of leveled 4* ready to ascend already.
As far as ascending 3*? 1.6 mil food and 200 same persona survivors, not a plausible solution.
