In here, we are going by the rule : "No Template, No Idea"!
Every idea must be put into the format before I comment on this. I have had many simple ideas, but I still ended up taking my time to put it in the right format. There is a reason for everything.
Yes, for the designers & developers to accept an idea, it has to be well thought through and well presented. They need to know beforehand, if the idea is worth, for them to spend their precious time on. Remember, they already have their hands full with their own ideas and with trying to keep up with the current game-bugs. In short terms : If you really want to increase the workload of the, already stressed, developers with a new idea, it really has to be presented for them, in the best way possible; As an, well thought through, "full fleshed" and ready to grab, idea put into schematic formation. And for that, we use the Idea-Templates. Most of the forum-staff won't even comment ideas, without the use of a Template...
There is a reason for the naming of the second thread in the Idea-section :
