This is turning out to be a lot like the no loot unless 1 star thread
Now I think having it specifically for outside town halls is a bad idea... that would be hard. But I think destroying the town hall should have some sort of benefit, if. you ask me. The town hall is supposed to be one of the most important building, no, THE most important building. Ever noticed how that is one of the 3 buildings you get at the start? Ever notice how cannons point away from them, no matter where they are? Supercell designed the game so that you TRY to trophy push. Hybrids are the ones who actually follow what you are supposed to do. The point of the game is to WIN, not intentionally lose. It really is kind of ruining the game.
My proposition is that much more loot (much more than the current 1000), like 10% of your loot, with a cap of the town hall level times 1000. Or a loot reduction/ bonus for destroying/ not destroying (not respectively:p) the town hall, or the other stars (the 50%).
