have you ever played a match of ace of spades, where everyone was griefing all the structures? (like in harbour2)
doesn't it seem unrealistic when a whole building disappears because of destroying one block?
my suggestion to improve ace of spades would be that falling objects are not destroyed on impact but are just moved to the highest solid block eg:
This way it is harder for griefers to destroy buildings, when the block falls the block should do damage such as when a roof falls on you, you would be killed instantly, other than be unharmed by tiny broken pixels. The physics are similar to minecraft's sand falling but the object is treated as a solid object, as opposed to single blocks.
if you like/dislike my suggestion please vote in the poll
BTW if this is implemented in future update please give credit to me
