A guild is a "An association of people for mutual aid or the pursuit of a common goal." Renown is "The condition of being known or talked about by many people; fame." So basically in ddo a guild is a collection of players working to level up the guild whether or not you want to. How does a group of players under a certain name just loose reputation everyday when people are most likely doing things in that guild every day that is heroic and etc...? If anything it would make more sense to have guilds loose renown for being squelched, and so turbine would have to have guild squelches. Of course then people could roll up toons and guild squelch guilds just because and there would be many flaws with this idea. Still this idea to me makes MORE SENSE then just loosing renown daily where your guild has daily heroes doing heroic things.
I say Remove renown or make the decay alot less
