Gently steering people away from coming to faulty conclusions that could be harmful to the developers is part of the job requirement, yes.
Now, I don't know whether you was talking about the idea about grenades itself, or the result of the poll, but for the poll:Yes, I would like to see grenades in the game - But only if they can be toggled on and off by server administrators.
would indeed be the best option of them all, all because the last sentence. Everything in-game should be possible to toggle on and off, similar to the admin panel in NW.
Line battles without artillery, cavalry or rifles, just as well line battles with it all should be possible by setting a ratio.
You are absolutely right about the poll in general. 27 votes aren't representative of the future community, but what is representative of the community?
Maybe it would be nice to have a ''If this idea reaches XXX number of votes, the developers will at least take it into consideration / commenting.'' similar to the way the White House, or GOG gives the people a voice.
You got the blogs, so might use 'em FAQs to answer.
Sometimes you cannot follow the entire community simply because it's too large to hear everyones opinion, nor make a poll where everyone has answered.
We kept grenades on NWRP despite 60% wanted them gone in 2016, while 70% wanted to keep them in 2017, and those responses were made by 100~ out of a community of 60.000 players even if we kept it running for months and plenty of announcements.
So in the end, it's always the choice of the developers. I don't doubt the OP knows that though, and I don't think he meant the voting was concluded. He stated the current stance in the poll in the wrong way. He might as well just meant respondents or users.
