Only the top 10 members in your alliance get any affinity solvent. This is one of the most important resources in the game to have early, as it gives you a massive advantage in every aspect of the game, and makes it impossible to catch up to players who have upgrades.
As it stands, it is better to have only 10 members in every alliance to maximize psychicore distribution. It also promotes being secretive and not helping people to build strong teams to compete in the overall alliance rankings.
Either scrap these 'in-alliance' rewards altogether or change them so that everybody in the alliance gets the psychicore, but higher ranks can get the glory medals, because as it stands you are incentivizing two different things. Building a strong alliance for overall rankings or building 10-member alliances to maximize psychicore.
And we need to have minimum 20 members in an alliance to even enter the sparkle tournament, so by default 10 of those members are missing out on 10k psychicore every week.
