First off, you guys need to tone down the rhetoric. I just suggested that in MY game I would likely not allow it as it stinks of cheese. I did not threaten the sovereignty of anyone else to do differently.
Second of all. If you're going to allow them to target the ground and do "splash" damage to all around it, where does it stop?
What IS the DC of the ground?
Does the ground get cover if someone is in that square?
What happens on a miss? Do you pull out the old grenade chart and roll a d8 to determine where it goes? Or do you just handwave and say it does nothing?
It just seems to me that by allowing this you are taking a spell that is meant as an attack on an object or creature and turning it into a level 1 fireball.
