So I'm wrong even though the only time you've ever been ganked in high-sec was already fixed by CCP?
Okay yeah, it can happen under some extreme circumstances and a few not-so-extreme ones. By the time you're done with the tutorial you've already got 6+ ships. Then the first arc they send you on brings in enough income to buy about 20 more ships.
I'll amend my earlier statements by saying that flying around high sec is no more dangerous than your average trip to the grocery store.
