There are almost no suggestions that have a GM mark on the thread that are decent compared to all the decent suggestion threads. What do I mean by decent? Oh, I don't know...threads that aren't copies of balancing a single gear horribly, marrige, dual wielding, unoriginal "new" weapons that would either be OP or crap if implimented to SK, iwantdiskthxbai, and joke threads and are covered by threads like the ones mentioned above? What threads are decent? Some include this ( http://forums.spiralknights.com/en/node/51858), this ( http://forums.spiralknights.com/en/node/53120), and this ( http://forums.spiralknights.com/en/node/68467). Did the GMs give 2¢ about the actual purpose of those threads? No! Should they have? It would have taken time off their day, but yes.
What I am saying here is that if you choose to create a topic in Suggestions expect the idea to be Graveyarded, even bumping the thread and adding tons of pages almost always won't make your threads more noticed by the GMs, but the players will always be reading the posts and will be attracted to larger threads.
Honestly I believe the point of suggestions is just so people think OOO is listening to them, and just for fun and discussing what might be good in such a game, more of a communal practise than that of them pinching ideas to use in the actual game
