Nice guide, but I think you understated the importance of heroes and spells. I used to farm in gold with an army, giant/healer/gob, that's fairly similar to yours in terms of training time and effectiveness. However, its viability decreased greatly when I was attacking with 0 or 1 heal spells, as I was no longer able to take on tougher th 9 targets. I noticed in your battle logs that you were using 3 heals on the tougher bases, which begs the question of whether you recommend boosting your spell factory, waiting for spells, or simply going in with 0 or 1 spells and looking for weaker targets.
You did spend more time talking about heroes, but how do you attack without them? From my experience, the th 9 bases you showed are a relatively easy 3-star with a hero or two, but I had to be almost perfect to get 75% of the loot if I didn't have a hero available, especially if I was low on spells. I recognize this isn't a dark farming guide, but even with hogs in your army, you're probably able to get enough dark to keep a hero (2 if you're especially active), and I was wondering whether you've been upgrading them or only using dark for lab upgrades.
