The biggest problem I had initially with the 4E conversion (as far as design went) was filling up/out the XP budget - ended up with a lot of extra creatures in each encounter and had to do some head-scratching to fill in the holes. Also, the Ravenloft module originally had a lot of "scripted" events that were best converted into skill challenges. That took a fair bit of extra work (perhaps because I am unused to building skill challenges, at least in 4E terms).
With WLD, do you have to build specific encounters with an XP budget, or just fill an area with X number of Y creatures and are just converting basically stats? Are there any skill challenges you are prebuilding or just working them out on the fly when the PCs don't rush into combat? This is a case of I'm curious to know how your approaching WLD - I think our differences were that I was converting a story-based (story-first?) adventure whereas I would term what your working with as a location-based adventure (story just sort of evolves).
Yeah, I think that might have a huge thing to do with it.
I'm pre-building a few skill challenges - one that immedietely comes to mind is a sort of stock skill challenge for exploration. While I loves me some theifly sneakery, it gets a bit stale after a while and having the rest of the group sit on their hands for half an hour while the rogue does his thing became annoying.
So, a skill challenge exploration with various events randomly generated is in the offing. I'm still not done with it, so, when I am, I'll put it up on the 4e boards.
As far as xp budgets, it hasn't really been a problem. There are a few rooms that had to be scaled back (Region A, forex, has a room with like 50 stirges in it) but, because of the minions, I can keep the numbers and the challenges surprisingly similar.
I have been making some changes as we go. For one, I've added a lot of verticality to the Dungeon by reworking a number of the maps. Also, since a couple of my players actually did this beast once already, I have to change around some of the bigger bad guys. No more wererat in region A trying to open a portal. Now it'll be something a bit different.
Once nice thing is the fact that I have 30 levels to play with instead of 20. If you played XP by the book, if the party started clearing out regions, they'd rocket up levels. This way, I can actually use most of each region without screwing up the balance on the next one.
I'm still pretty early into things, but, it's going pretty well.
