First I want to start off by saying, that clearly you don’t live in Null if you’re asking many of these questions…
I mean again, it’s not affecting Rorqals (which can mine as much as an entire fleet of barges) so I doubt that’s being affected. Mineral prices won’t change because you have these mining behemoths that are super hard to kill still bringing in tons of ore.
The only thing that will be affected in large, are dead space modules and officer loot, as I can tell you the majority of 10/10’s that used to be auctioned off on the alliance trade chats have all but vanished, and only mildly replaced by 8/10’s b/c people are VNI ratting and doing 8/10 anoms…
As for defending your space, unless you’re Goons, which I can tell you both from talking to quality roamers who have come into my space, as well as roaming myself it is nigh impossible to stop and trap roamers. Will you kill some? Of course, but will you get them all without a Boson on every gate…? No…
All this has served to accomplish, is A. make it almost impossible to be in a smaller alliance, and I mean you literally have to be in a BIG BLOCK like Goons to still operate on the same lvl (which they are…) B. make eve like a job, where now instead of just showing up for hours to float around for CTA’s you’re having to float around for hours to defend your space, or work together to make money (heaven forbid you’re not all on the same TZ either…) and C. given small gangs 2-10 players a free pass to go anywhere and do anything anywhere anytime (outside of Delve)…
