The suggestions forum is a wondrous thing; it has the potential to enable players to tell the devs what they want in the game, and for the devs to deliver. E.g. battle sprites.
So before you post suggestions in this forum, take these points into consideration:
1. Will your suggestion actually improve the game? i.e. increase enjoyment of the game, increase actual playable content and add new things to do. There's no point in having a billion new slime type monsters or a super powerful new sword that only vanguards can get, etc. These things do not add to the game. A game is a carefully crafted and balanced system with restrictions on some things, so maybe think twice before requesting that new weapons and monsters are added purely for the sake of them being added and because you thought you had a good idea.
2. Know that OOO pays professional game designers who work to balance the game and come up with good gameplay ideas, and that what you think is a great idea may not be. Don't bother to fully flesh out a concept down to effects, damage, and colour. They have a design team for that, so just suggest a concept or idea. And don't be bummed out and complain that the devs ignore the suggestion forums. If an idea is good and is backed by the community of players, the devs will notice and implement it. Again, E.g. battle sprites.
3. Everyone hates walls of text. Break up your suggestion into small, digestible summary points rather than an essay on the merits of your idea. Keep it concise. More people will read your suggestion, and thus you will get more feedback.
4. Know that people will almost certainly criticise your idea, so be prepared and don't whinge about it. This is a forum; you can voice your idea, and other people can voice theirs. And if 50 people are telling you that a certain aspect of your suggestion sucks, it probably does. Accept suggestions and criticisms and take them into account. No complaining that the suggestions forum is a 'hostile environment'.
5. Think about the feasibility of your idea in terms of implementation, cost and time to the devs. No, the devs are not going to spend weeks of solid work hours re-balancing the system for an idea that doesn't improve gameplay.
6. Don't suggest that obvious problems everyone knows about need fixing. E.g.: "Heating needs to be fixed!!", "Moonstone and valestone are useless!!!", "Bombs are underpowered!!!". These are known problems, so don't bother posting them.
7. Don't post an idea and then state that you 'know it's a dumb idea' or 'isn't feasible'. Don't post anything containing "I know it's dumb, but wouldn't it be cool if..." This is a forum for suggestions to the development team that could potentially be included in the game. Don't flood it with posts that aren't legitimate suggestions.
8. Don't bump dead posts! Let them die graciously. If your post gets no replies and moves on the next few pages of the forum, it doesn't mean no one saw it or read it. Don't bump the post or beg for comments and feedback.
So go through these 8 rules before you post, and the suggestions forum will be a better place.
TL;DR: Just read the bold stuff.

That reminds me of this thread:

I get the feeling I could communicate on the forums entirely through links to older posts that have said the same thing.
