Field Support Tower level 2: Kill switch Very gimmicky. It costs 5 energy to use and only 15 non rechargeable energy for 2 towers, does 15 dmg with a 2 second delay. The only thing i see flawed in this is that it deducts from teammate's shields. You can cause heavy rating drops in-game and its not fair to the other players. I'd rather the kill switch just bypass shields and directly damage HP.
