It's not negative feedback if it is contructive. To say "that idea sucks" is just negative and of no use to anyone. But if it's "That currently has no apeal to me, i dont like the idea of vulcans being so violent in your missions" then it's constructive and thuse USEFUL.
We cant post and hope people rub our egos and tell us we are great, but we can ask that if there is something you dont like. You take the time to explain why it doesn't work/puts you off playing it etc. Thats helpful feedback even if it isn't always what we want to hear. We cant ask for more than that..honesty but with a little care on how it's phrased. Personally if people tell me they dont like my idea and explain why, i will be greatful to them for taking time out to even bother repsonding to my mission. But as i said saying "thats crap" for em would be dissapointing.
That was basically what I was trying to say. Thank you for putting it in a more eloquent wording.
