Kventin, I enjoy playing with rebuilding from any level, although, of course, it's more imbalanced than in HotA.
That's not true. Rebuilding requires a day's worth of construction, so unlike in HotA, you won't be doing it, say, in the main on a Jebus Cross right away. Level 4 and 5 almost always require finding Town Portal and Dimension Door, whereas in HotA on a level 4 GM you choose from two spells, here you get both at once — only in HotA, if you happen to get, say, Resurrection or Armageddon, you can keep it and rebuild the second slot; here, that is impossible. Moreover, in HotA there are noticeably more resources and they are significantly easier to obtain, so overall, rebuilding is more of a freebie in HotA.
