More rewards is always better, plus it gives more motivation 
I’ve noticed that in the alliance leaderboard there is a 1, 2, 3 ranking up top. Do you mean prizes for the top 3 and other lesser prizes for everyone else?
I mean reach a certain amount of points to get a reward but make it higher because its the sum of points of alliance members
They seem to want to keep that mechanic to the alliance boss battles like Ultron.
Unless they lock rosters, you’d have players bouncing from one new alliance to another, getting many multiples of whatever the progression is.

love to see it but never happen just think top reward say is 90k top reward for team would be like 1.5 million
