2222 suggested the other user to drop at 1000 trophies not a 1000 cups less than your range. thats too much loot difference. im hovering around
4700-4800 range so even if i drop 1000 cups it will still be a big loot difference to me. and i assume most f2p players who like bb, already hav saved many books to be used at needed time so there wont be any problem wasting loot during battlefest event. i used 2 books of fighting, 1 book of everything & 1 book of building. granted, you could drop 200-300 cups tilting, while grinding challenges but dropping purposely that too with your main account? no way. that would only suggest you dont care that much about bb.
now this does not apply if you are a gemmer as you can gain any kind of loot you wasted while dropping.
