TH8 in champ3 in similar situation
I had to do war style attack every 1/1.5 hours, 4 attacks per cycle, very hard to find th9 that I can attack with decent trophies and always lose 30+ cups to master league players.... not many th9s in champ and above looks like, all th10,11.... but still champ3 is good place to stay as my loot is almost always full thanks to bonus and I can 2 star any th9 with sleeping heros. but it is time consuming and stressful, I have 2 other th8 accs in silver 2/3 and farming is so much more fun.
