Castles have walls. You cannot see over them unless you do enough damage to get in a little bit and have a peek. even 1 or 2 small attacks against a heafty opponent may yield nothing.

Great change imo. sick of the idiots sending 10k warriors and rainbow just to scout.

And a high level player will be hard to scout, and may take multiple times to break that defence and scout them successfully.

Stop whining because you are losing more troops than 10k warriors now.
