Disclaimer: I don't pretend to know how the raiding matchmaking algorithm works so maybe none of this makes any sense.
Currently, the number of people online seems to affect the amount of loot people find. When there are fewer players online, there's more loot, when there are more players online, there's less loot. I notice that in my time zone, loot is always much better in the morning than in the evening.
Is it possible to modify the matchmaking algorithm so that loot PER PLAYER is more or less kept constant? So whether there are more players or fewer players online, the amount of loot they would find would be more or less the same.
And I'd also like to point out a fundamental clash between Supercell's aims and the game mechanics:
The aim is supposedly to get active players to clash with each other. However, the game mechanics are such that active players can't clash with each other unless one is online and another is offline. So for loot to be constant, the number of players offline needs to be well spread out. For example, if there were 90,000 active players, they could only clash with each other if 30,000 went online for 8 hours, then went offline, and another 30,000 came online, then went offline, and then the final 30,000 went online for 8 hours and then went offline.
If most active players are online at the same time, then they cannot clash with each other. So if there were 90,000 active players but 60,000 were online in the first 8 hours, those 60,000 would find very little loot. 8 hours later, if they all went offline and 15,000 came online, those 15,000 would find more loot.
Therefore, if you raise loot across the board e.g. higher level collectors, players who are online during off peak hours will benefit more.
That's really my reasoning behind my suggestion given above. I think it could only be good for the game; many real world businesses do it. Factories scale up production before Christmas, restaurants hire more servers for lunch and dinner, transport companies provide more trains and buses during rush hour.
