Bump.
Doesn't anyone out there besides Graeme (and btw, thanks Graeme

) have some answers to Incognito's original questions? I've also been wondering about dome strategy, myself, and would appreciate some insights.
One specific question, I've looked that description for the blood dome (Dome of Corruption), and it says that occasionally the mages inside the dome are attacked by Horrors. This sounds like a pretty expensive cost (all depending on the frequency of Horror attacks, of course) for keeping up a dome - do any MP players out there like the Dome of Corruption, and find it worth the occasional mage?
