Not chiming in the overall conversation between you two, but I wanted to point something out: now that capital ships can take gates, there’d be no need for cynos in hisec if we allowed capital ships to operate there. They could jump out to cynos lit in low/null, sure, but in hisec they’d be stuck taking gates like peasants.
I’ve seen a few different proposals to allow capital ships in hisec (and even have one of my own floating about still), but I can’t recall seeing any that call for hisec cynos, not even the topic at hand.
