While it theoretically is more dangerous than Nullsec with the lack of intel, blue doughnuts, and Local, it’s also easy to reduce the level of risk by critting your static(s) and rolling off the random connections. Good luck getting enough ships through a crit hole to fight a battleship or capital ratting group successfully.
It still won’t make you “safe”, since a new wormhole could appear at any second. A hunting group that’s on the ball would have about five minutes to get to anything stuck in siege mode, but subcaps could be away before the hostile fleet even warped to the hole if they run away as soon as the new sig spawns. The majority of targets you’ll find are going to be subcaps, so you’re really left hunting the careless or the inexperienced.
If you do come up with something that is legitimately a good thing for w-space and that would increase outside interest in w-space, aside from Null bloc farming, it won’t be implemented. If it did bring new blood into w-space, then that is activity that could have gone to Nullsec. Or even worse, that could have been Nullsec activity that relocated to w-space.
CCP won’t intentionally encourage that and will do their best to prevent it from happening. Nullsec is CCP’s baby. Null fleet fights bring that “Wow” factor, and talks about the shifting political alliances and who is sleeping with who make good soap operas. W-space will never be as useful for an advertisement campaign as Nullsec, and that directly translates into CCP income.
I suppose if you can find a way to increase the appeal of w-space enough that it draws subscribers in somewhat comparable numbers as Nullsec, you might have a chance.
It’s a vicious cycle: don’t want to spend time, effort, and money on something that doesn’t directly generate revenue, but it’ll never develop into something that can generate revenue unless you spend time, effort, and money on it.
