Man, talk about pointing a finger and three point back, you haven't accepted the possibility of you being wrong yet! And bringing up new evidence and clues for review is a perfectly rational way to discuss something.
I am completely prepared to acknowledge being wrong. I just don't see it here. It was tyranids that got me into the hobby ten years ago, I've looked into their fluff from front to back from sources including the Imperial Armour books, every codex they have as well as any novel I could get a hold of featuring them.
I'm not just opposing your idea because of dislike or anything, I genuinely do not see it as being a possibility. That's all.
I'm sorry, I thought I posted this in the "Homebrew Fluff" section where you can make up your own fluff. My original post and the topic for this thread was about a loose end in the fluff that left an opportunity for a new thing to terrorize the galaxy. And the crazy thing is that it looks like Kreugar was trying to give me pointers on how to develop the idea, which I nearly forgot about because I was letting you derail the thread.
Yes, but generally homebrews still fit within the boundaries of the lore. Also, you did ask what we think, so it's a bit rich to react this way just because flaws with your idea are being brought to light. That's generally how feedback works, you have to accept good and bad.
I'm going to get this thread back on track and if you'd like to contribute that's fine.
Sorry, but I don't believe this ever left topic. You asked what we though of Chaos Tyranids, and the consensus seems to be that it ultimately won't happen. You are the only one trying to justify the idea.
