Interesting playstyle. If I wasn't so enamoured with Mortal Voyage, I'd probably give it a go.
Got to say, though, that being able to retreat and reenter fully reloaded on HP and SP an unlimited number of times is, to me, much more of a crutch then using shrines.
In MV we use every other shrine, and it seems a good balance. We don't have as tight equipment restrictions (while there's very little we buy, we can use most everything we can pick up), but then again, it's permadeath EDIT: and we only play quests hard or elite at level or lower.
The Core is, debatably, even more hard-core.
As Talltale suggested, if you don't find a steady stream of guys to play with your way, you might want to check out one or the other. EDIT: Besides, I think you'll enjoy getting out of the harbor more often. To my mind, even fresh off the boat, with a few masterwork items, the harbor on normal is probably too easy to really have fun with once you develop your skill set.
