Was it ever worth to write essays? I thought the only language they speak is money.
Considering the effort they expend, depending on your view "caring now" or "pretending to care", I'd say at the very least those who openly criticised GW had a direct impact. It's amazing what some people will put up with if nobody says "something's wrong here". Criticism is important. I did my bit, maybe it helped. My goal was never to get through to GW. I never felt I should have to explain to a company charging money for every single thing they do to be told they should be doing it significantly better, to you know, maybe come close to matching the price they're selling it at. I never thought GW needed a bunch of free advisers to tell them where they went wrong, which is pretty ironic considering that's their primary mode of fixing things at this point. My opinion on the importance of criticism hasn't changed, I've just finally accepted the futility of it. GW makes shit games, charges a fortune for it, and people who just need an excuse to push expensive plastic around give them money. The cycle repeats.
I wrote essays because I used to care about this game. I don't anymore. It's pretty obvious that writing quality is going to remain the one thing GW wont hire the talent for. To be fair, the talent probably wouldn't touch them with a ten foot barge pole, but then that's their fault anyway.
