Greetings.
Keeping this to the point. I think we are getting close to the time when we need another 30 secs added to the attack timer. If the xmas update includes more def buildings upgrades. More wall lvls. Maybe more buildings. Higher lvl heros. All this takes more time to clear a base.
I suggest to supercell that if you are planning on the above changes-please include more attack tine. Gotta keep it balanced. Last attack time increase was long ago.
