I've seen a number of guides that say that Balloon + Minion is a good was to farm DE. What level of each do people start using this strategy? I am TH7, have my Balloons to level 7, about to complete upgrading my minions to level 2. Do people use balloon + minion at TH7 or it normal to wait til TH8 when you can get lev 5 ballons and level 4 minions? Thanks for the help
