I was up in Masters 2, was using my typical Lavaloonion to loot up there and was making decent progress, especially for gold.
But I've just dropped down to Gold 2... and damn son, the loot is outrageous. I've tried coming down this low pre-update, but I'd only see shitty bases (th7 and below) that weren't worth my time. Now I'm seeing TH8 at the lowest, but often TH9 and TH10.
I'm using an army I've called GoBAM! (BAM with Goblins, basically) and I've been pulling in 150-300k of Gold and Elixir and 500-1500 Dark, with each attack. If I boost one barracks and one dark barracks and I can basically just attack constantly. Boosted, I can easily earn a few million per hour. It can take a little searching to find an inactive TH10 that's got enough loot (skipping maybe 20 towns), but even still, I'm skipping towns with 150k, looking for 300k. I could probably loot the 150k towns and still make a fucking killing, with how quickly I can attack.
I'm basically getting the same loot I was getting in Masters 2, but far easier (usually just draining mines/collectors), with a MUCH cheaper army and far more frequently. Yeah, losing the bonus sucks, but all the other perks make up for it.
Barching (or GoBAMing) down in Silver/Gold isn't the most entertaining way to play, especially after getting used to the Shark Tank of Masters, and I imagine I'll get bored of it reasonably quickly... but it's fucking effective for getting insane loot.
