[Must Read] Avoid accidental troop drop.
Have you ever tried to click "Next" or "End Battle", but you ended up dropping a troop? Yes. This is really annoying, especially when you are trophy pushing. Why does the first troop has to be selected automatically, with the white borders?
My idea is that before you start attacking, you don't have any troop selected at all. If you try to drop a troop before selecting one, a red message will pop up in middle of the screen saying: "Please select a troop before attacking", or something like that! This way, you will avoid dropping troops and losing 25+ trophies.
