New attack button in online attacking (not clan war)

Hello ;)
My friend and I were thinking about a new button when you attack people (not in clan wars) online.
When looking for a base to attack you are scouting (just like clan wars) and when you find your target your click the
"Attack" button (like clan wars). You only get 30sec to decide if you want to attack the target and if you do want to attack the target you click the "attack" button and you can attack :p. This prevents when you are clicking the next button and you accidentally place a troop down and you didn't want to attack this person. Please think of this as a solution to these problems.

Thanks S3ssm ;D

Indeed dropping a troop by accident is annoying, but rather than adding a new button it would be simpler not to have any troop selected by default. If you want to attack, you will have first to select a troop type and then drop them. If you have no troop selected, touching the screen will pop up a message asking you to select a troop type, but the war will not start.

or on default no troops are selected during the start.

so if u click anywhere u wont spawn any troops at all, unless u select them and then click on a specific area
