"Loot is easier to get at town hall 8 than town hall 9"
This is a statement that I've seen around the forum, and it's completely untrue.
Loot is much easier to get at town hall 9 than town hall 8.
Town hall 9 gets level 6 barch.
Town hall 9 get 20 extra army camp space.
Town hall 9 gets the archer queen.
WHO CARES about the loot penalty? You unlock so much huge attacking power at town hall 9 it more than mitigates the loot penalty. These troops are also strong enough to push to much higher leagues so you can get more dark elixir and league bonuses.
Town hall 9 has an easier time getting loot than town hall 8. Assuming you've kept up with your troop upgrades.
