If you're TH9 with max minions, and you use 30 per raid at 10 DE each, that means you need to clear 900 DE per raid for the minions to be covered by the higher attack frequency. ex 3 raids at 900 DE = 2700 DE vs 2 raids at 900 DE = 1800 DE, minions give 900 more DE, but cost 300 DE per raid (900 total) and it balances out.
Do the math for your particular minion usage level and DE earned and see if it's worth it. If you're in a high enough league, there's no reason not to use BAM as the league bonus alone from the extra wins pays for the minions.
