While my opinion might be considered somewhat biased. I try not to be.
I think keeping GWi as spawning point for new players is better than directly to the main land. As has been said. At least GWI offers some single player activity. And it slows a player down a bit, though not much, before seeing how empty MD currently is.
What it does need is an automated narrative/guide. Since there aren't enough active helpers to have a 24/7 presence. And follow up quests for the various exits.
For someone actually stuck. Or old player just popping in. Sure port them out. (easy enough to make a clicky that offers insta travel choice to anyone above a set ad minimum)
@ Ledah. The rope is not hard to get. It is easy to miss though. (It's just lying on the ground somewhere ) The Heads option is one of the oldest possible ways out. But it was disabled because there was no point. As you pointed out. Not enough people... And riddles... well they are tricky, some you get instantly and others you just can't figure out. But I'm glad you enjoyed it anyway.
