Some might say this is just a game, but imagine the scenario in real life battleground: "If I aim to the moon, to third crater from left side of it, while I stand exactly at this point, this dropshot will go inside the building through the hole that is in the roof"
Don't know where you'd need to be aiming at but I assume it's something up in the sky.
What comes to those dropshots and G in general - I hate them. Goes to the same category as flashes: use them if you have no balls
