Poison and 30 second

Hi
I have a criticism if defending troops run the poison spell so how can we use this spell? Its better to remove this spell from clash of clans.
and about 30 seconds how we get 3 star in th 8 and more? Bring 30 seconds back
Ali
Thanks

Come on man, use your brain and think. To use poison now it is harder however it makes defending CC troops way more useful. When the poison is dropped just make sure there are a few troops of yours around to keep the CC troops inside the poison spell. As for the 30 seconds, I do agree after TH8 its hard to get a 3 star attack in 3 min. But back before the 3:30 attack time everyone did it, so we can do it again.
