Everyone now know and probably experience accidentally deploying a barb on a base you don't want to attack and lost hard-earned trophies. It's so annoying right? I found a solution for this please have time to read.
The accident is mainly because the player tapped outside the next button. We can't blame the players for this because that player probably got big thumbs, small screen, or sleepy. But the point is he didn't intended it. A probable solution for this is to either make the button bigger or put an attack "que" (like the attack button during clan war) so that this could be prevented. A que I thought of is to remove the default troop selection. What I mean by default troop selection is where the barbarian is selected by default and is ready to get deployed in each view of the village. If this is removed, meaning no troop is initially selected, even the player tapped outside the red area, no troop will get deployed - saving the player from accidental troop deployment. Now when a troop is selected by the player, it means that the player now do really intend to attack.
I don't know why SC still doesn't implement such feature. Clan war already got it anyway. They could just add the button for attack in clan war if they're lazy.
It would not make the game any easier, I mean it's not like a 'cheet', so there's no reason for it not to get implemented. That's all thanks!
