I've been TH9 for a month now and just finished upgrading most of my core farming troops (lvl6 archer, lvl6 giant intended for base penetration to farm DE). I was wondering at what level are minions worth using to farm as a TH9 raiding other TH9's and TH8's. I rushed so at the moment they are level 1, only my normal farming troops are maxed, at what level should I start using minions to farm? I'm guessing lvl3 minions?
