As long as we will have any window for 'safe' digging, everybody will be safely digging - except newbies and 'too honest' people like me :/ - no war ever, gangs get their stuff peacefully, newbies get shot by PK, just as always, only worse :/ As long as there are alts, any kind of 'safe digging', or 'Enclave hours' will destroy the whole 'HQ resources' idea. HQ - means those which you have to dig with an alt. It won't be like 'it is easier/faster to use alts. It will be like 'it is nearly impossible to do it without alts'.
Unfortunately people prefer to go naked with only a sledge just to have more minerals and when it comes to getting stuff - awoid every danger there might be. Another mine - yes, but not guarded.
blahblah -> just get info, when some not PKing gang is going to mine and tag along with them. Or gather around with some people from NCR or whatever. Damn, you're not a newbie, if there is some obstacle - deal with it.
HIGH-END stuff should be hard to get. What fun it is to just go and make 50 best CAs and keep them lying in your base (as it was before the wipe). I mean - does 30 spare avangers are so important? Does EVERYBODY has to run around in best armour and best weapon after certain fixed number of clicks in the game? Does TC wars need to look like 15CA's + 10avangers + 5snipers vs 15CAs +11avengers + 4snipers? Is it really so important to make everything without a problem and get bored after stuffing your base with everything you may ever needx50?
If you want to make enemies, try to change something.
Ah, but we would also know when those times are and could just sit there checking everyone out, banning where appropriate
