Super cannon

I get attacked a lot by th9 and 10 and I am in gold II. Also I have a big problem with giants mostly because they have a lot of health because well town hall 9 and 10. they use giants and wizards and always three star me. so I want it to attack slow like 3-5 seconds and do like 350-500 at level 1.(the cannon not the giant) I think they should be unlocked th7 and be very expensive. This might be two OP so tell me in the comments or if it should be unlocked th8 .

The best way to reduced getting three star from th9+ is to keep improving your base with the right layout and stronger defense. I wouldn't expect to see much more new defense for Town Halls below 8.

Upgrade your defend and change layout,dont rush your village.enemy may be cant easy with your strong base maxed
