I second what Olywynn and another(s) said about expanding the depth of extant regions. I'll admit that I'm still a low-level player across the board, but from (my idea of) a developer's perspective, if you've managed to "lock down" regions for which you don't yet have the resources to open up to the playerbase, then don't open those regions up until you -have- to. And you don't -have- to until you've developed all of the potential of extant regions such as Barovia and Dementlieu. Particularly since Barovia is the focus of the server, I'd love to see every significant site represented (and more than just as a "glimpse") -and- internally relevant. I prefer to have each region potentially be its own play area across the levels rather than a WoW-esque railroad of "from levels x-y, be here, and from levels z-a..." (I'm not saying RLoft is that, but simply illustrating the extreme end of that spectrum). I'd love to see reasons for high levels to exist in Barovia (without, of course, trouncing on the lives of lowbies).
In any case, be careful about opening Pandora's Box when there's already Dionysus's Nose and Hera's Teeth to finish painting.
