passive skills sound fine to me, but they had better wipe on every death, unlike items you can't loot skill from yourself xD being able to afk to gain them by doing nothing is stupid, if someone wants to waste hours shooting then healing a friend, let them. When he gets killed and loses anything he gained it'll just be wasted time on both their parts. That way people that are actually doing things will get some extra benefits from their actions during their life, and if they die, well they're dead .
