1. Laboratory update. It would be cool if guys let us upgrade multiple troops at a time,let's say starting from th7(where you get your 1st dark barracks)you will be able to upgrade 1 elixir and 1 dark elixir troop at a time.
2. New spell. A spell that makes evry troop who walks inside the AoE unseen by enemy defenses for a period of time(does not affect heroes.cos i think that would be too much 😀)
