Warning, ranting of a madman ahead.
Simply, the entire year has been awful for many people with an awful election season spilling over into everything else in multiple countries, many deaths both familial and celebrity angering many, and GW continues to behave in a bipolar manner despite its new CEO. The ghost of Fantasy also haunts all of us, making many of us behave like an alert Jackrabbit, jumping at the slightest sound and heading from the hills as they anticipate the worse, because GW has still given us zero reason to assume of anything good. There is no reason for optimism when the trend is only just improving, and that other fandom you might had had stepped a toe into just got blammed only a couple years ago yet, and you're worried you might be next.
Then there's the game itself, and 40K is frankly, objectively, a terrible game. It is in desperate need of being fixed or even completely done, but I am completely terrified of the result of such a fix if done by GW because I have absolutely zero faith in them. And, at least for me, these new "toys" are actually the problem itself, because the constant increase in game scale and models just piles further imbalance and money on top of what is just supposed to be a skirmish game, running on skirmish rules. It's why I haven't painted or even assembled much yet (although partially out of fear of ruining absurdly expensive models and indecision of where to go). Like the whole new Fall of Cadia bollocks. I now have to go back to the drawing board with my Chapter to make sure they don't end up in the middle of the damn warp.
People talk about how change is good and inevitable, but here's the thing. The change we're getting? We don't need. We don't need Primarchs, we don't need new demi-titans, we don't need new baneblades, space marines, or chaos space marines. What we need is new rules, and nothing else. What we need is so that every single unit is just as viable as the next. What we need is there to be no "bad" army. What we we need is balance, and GW sure as hell ain't giving it to us. While 8th Edition might herald a dramatic shift in the rules, m faith in GW accomplishing this with every single army is nonexistent. If they can pull it off, that'll be grand, but hope is the first step on the road to disappointment, as Dawn of War says. And I've fooled enough to know that the next time is on me.
That's just it though. Much of what you're mentioning is related to the people in your club and not GW and certainly not the BnC. The army list subs are where those things should be discussed and hashed out. Not every news and rumor thread. Letting bad rules pollute the board poisons the well for everyone not interested in rules.
