I entirely agree with Wendywu-- in fact, the depth to which the exclutivity of the IDS allows me to go with my deck gives, rather than takes away from, the sense of magic and wonder I get from it.
Hunter-- this isn't pointed towards you, but just in general-- I can't really understand the motives behind voluntarily joining a group which, simply by name, is meant to be intensive if you find the idea overly restrictive or counter to your most productive style of learning. Our awesome IDS organizer and thread leader thorhammer can correct me if I'm wrong, but I do think that exclusivity to one deck is a big part of what makes IDS IDS. If I've got the history correct, IDS is an offshoot of One Deck Wonder, a study whose whole purpose was exclusivity.
I believe that the reason there are currently two different study groups in the forms of IDS and PDR is so that IDS can be an exclusive, intensive study of one deck, while PDR allows you the freedom of working primarily with one deck while using others on the side.
None of this, meanwhile, is being forced on anyone. If it doesn't sound like something you'd be into, then there's no reason to join.
As Le Fanu said, if you aren't enjoying the process, what's the point?
