Buff active party grinding and nerf leeching with afk timer

Leeching is a blight on the server and most ways of buffing party grinding end up benefiting it, so why not double the party experience bonus (10% -> 20% duo, 15% -> 30% trio etc), but reduce exp gained if you haven't damaged a boss or killed anything in the past 30 seconds or minute by some percentage (40%? idk).

no, this wont eliminate leeching as people can stand up from their chair and kill something once a minute, but it would be annoying enough that many leechers would rather actually play the game instead

basically party grinding is social and fun and leeching is dumb and stupid and everyone hates seeing 9 smegas a minute for buying or selling leech
