Since release it has become an increasingly common practice to keep a Magic Find (MF) set in your inventory, and swap it in shortly before a kill. Philosophically we don't have a problem with the practice. While players getting more Magic Find for their kills isn't a game breaker for us, many players have said they don't enjoy doing it but feel the benefit is too large to ignore. Since the call for a solution really comes from all of you, we'd like to invite you to chime in with your opinion on what the solution could be.
It's worth keeping in mind that if we do implement a method to alleviate gear-swapping in combat, we'll simultaneously be looking at ways for players to get an added MF bonus to compensate.
