I find that if my base is torn to Hell, I gotta fix it before I start fighting. For some reason, I need my base to be nice, the ground can't have random holes put in it or bricks just scattered all over the place. Now, some little punk wants to run past my wall with a Trench Digger while holding down shift, space, and left click, I gotta kill him quick before the minutes of rebuilding pile up. I know the rule wasn't put up for my sake alone, but I can tell you it really pisses me off when my work gets picked to pieces. People can dig tunnels under my wall, or platforms over it all they want, as long as it is done to invade and kill like everyone is supposed to, but they shouldn't be able to vandalise just in the effort of making people mad.
