i learned a hell of a lot running shuke up to 220+30. I know a lot more about the ins and outs of things, and strangely, missed the fact about loot penalties on collectors.
None of that matters, none of the ability of th6 to hit you big, none of it for penalty on th6 matters. At the end of the day this is a TH8 and up game, that's who is active, that is who is raiding and that is who you will be raiding yourself. TH6 and down is for noobs that quit or don't know any better.
All this bull#### about hitting th6 with th4 is a waste of time and worrying about how a th8 is gonna come smoke an undefended th5 base. Guess what, with CC fur coats and 200 ####ty barch you can 100% many, many TH8s.
Loot rolls in and if you get raided, who cares. I was forced to, but learned how, to work around knowing I'd be 100% every time I logged off. Obviously, on occasion I "cheated" with bluestacks, but those times were really, really rare and optional. I think now knowing what I know I could do it with a phone only.
