This is a feature that is very intuitive, and it makes perfect sense for the Clash of Clan developers to sincerely look at implementing it as a core loot impetus.
Plainly stated: The more consecutive wins, or stars, (within an allotted period of time) gives a higher loot modifier. Someone winning 4-5 games consecutively should be entitled to perhaps a slightly higher percentage of loot for each consecutive win.
Another consideration I had was ending this streak when you lose a star from an attack on your base. There are many different types of systems to pick from and algorithms to decide this loot multiplier.
Ultimately, the win-streak modifier would leverage the loot received from the battle with the cups also received/lost. This strongly discourages people from leaving TH on the outside (which does not align with original developer intention), and it gives people a motivator to continue to WIN attacks, instead of floating in a certain bracket for best loot optimization.
Possible Concerns: Room for abuse - perhaps dropping trophies to very low levels and winning a multitude of games in a row could arise in order to stack high multipliers. My suggestion for this is making a multiplier more significant the higher in trophies or stats the base attacked is, e.g. a 200 trophy range base would give you a lower multiplier than a 2000 trophy range base. This would add another significant layer to the war-loot bonus which currently does NOT compensate for loot difficulty at higher ranges. Farming at lower trophy levels seems the intuitive approach for anyone with a familiar understanding of the game; this is not how it should be, and I am sure it does not correspond to the original intentions of the developers.
Hopefully, my words actually mean something. This is a feature that I strongly feel would strengthen the integrity of the game and give it a fresh perspective, while also introducing some variance and intrinsic motivators that are currently deficient. Thank you.
