I’m in nullsec, and wouldn’t call myself poor. I’m very recently broke because I spent all my ISK on a fancy new ship you chucklemucks aren’t gonna get a chance to blow up yet, but I’m not poor. It’s entirely possible to get 2 billion a week in nullsec without trying all that hard, but it does take some pre-planning and good practices.
To the extent I understand the letter, there are veterans (call them bittervets if you must) who object to the new changes because of how they see it will affect the game longterm. I don’t pretend to fully understand what it is they’re upset about; I’d rather see the list of specific changes they have in mind, but that’s my 0.02 ISK as an individual, not as a representative of my corp, alliance, or coalition.
