I think it would be nice to get an ingame token of appreciation if you helped to make the game better by submitting minor or major bugs. Yes, i recently submitted one myself earlier today, but that is not the point, its just where it got in my mind.. Imagine the flavortext like "Earned by getting a like from the dev's on the forums." and then below "the dev's and mod's regularly give out likes for players who helped to make the game better by submitting bugs and such." Just dont make it 5 value so it feels obsolete and people will appreciate the thanks and for some, it might be the reason to finally submit something no one else has noticed when they would usually ignore it.
