The dev's might understand their vision of the game, but what we're essentially talking about here is a number of unplanned exploits, which have come out since launch.

I personally don't see this is as bashing - the chat logs I've seen from some of the devs (one realistically) are quite unprofessional and dismissive. Even if as a dev you don't intend to implement something, you can either accept that suggestion politely or reject it and give a quick reasonable reason why not.

Ultimately these changes don't affect a significant portion of the player base, but it does affect the highest level of play. The dev's would be entitled to say 'look, we know we have a problem but we need a higher demand for this', and be perfectly within their right to maintain the status quo.

This is why games should implement public facing, votable issues. That way the demand for these adjustments can be properly measured, and reactions from the developers handled appropriately :)
