A lot of that is good, but what's the point of event 4*s here? In FKG you can use the event golds for specific purposes (buffing up whale ships, for location-specific maps, or building a team all of one type for boss-fighting). Here, event 4*'s are just going to sit in my reserves and never see the light of day. Ever. All the 4*s on my team are already a much higher level and I'm not about to downgrade to a different 4*.
