I'd really like to have some incentivized skirmish play!!
Also, I'd LOVE to have an in-game feedback. I think that would be great for when dev's want opinions on what content people might want to see or if people have an interest in seeing something they might want to make. Maybe even provide snippets of info to keep people checking on what might be coming! (i know they already do the news) I think an in-game feedback would just yield more participation that the forums. food for thought.
