Ok why is drop better? Lets say you have a lev 11 infront of you. Your the only person and you need to kill him. You can choose maxxed piano or maxxed TNT. If you throw the TNT you have to get attacked in order to activate it with lure. Then of course lure might miss. If you choose the piano it may hit the first time and kill him with no hassal. But of course it may miss. Still it is better taking that chance then taking the chance with the TNT.
