The OP"s attitude is wrong on the very basic level. It"s the "null is too safe" argument.

You see, you are assuming that nullsec is supposed to be some kind of Somali waters while in reality it never intended to be such. If you and your gang find it difficult too pass unnoticed and gank people that are actually holding Sov in a constellation because you are reported a few systems back on intel channels. then it works as intended. If someone pays attention to local and manages to get his battleship into a warp in that 10 sec window then he deserves to get away.

What you are doing is actually forcing a game mechanic that would further allow small gangs or even solo pilots to harass and disrupt activities of larger entities, which is ridiculous because you know, nobody gave them the space for free

They worked hard to earn something they can call their own home, so obviously it comes with some perks in terms of security.

And if you want to introduce null-dwellers to the concept of risk then Eve gives you plenty of tools. Bring the big guns. Camp the system. Trap their assets. Eventually take their Sov.

But for ffs dont expect to make people living in a heart of their empires miserable with a few mill ship and a bunch of punks waiting on the other side of the cyno.

To wrap this up:

If you are choosing sov space as a destination for your roam expect to have a hard time ambushing people in a fight they find unfair. They are at home and you are an intruder, YOU being in disadvantage works as intended, I dont know where did you get an idea game mechanics should favor gettimg easy kills anywhere near player - controlled areas while being solo/ small gamg
