Well - I guess having the rangers cast magic-user and druid spells was how FRUA worked, too, at least.
I guess that one could have importing from FRUA to DC still work with added monks, illusionists, half-orcs, etc. - might get more complicated, though, I am not sure. But if adding these guys is a bit off from the original DC vision, well - I guess a hack will do nicely, then. (If it doesn't contradict too much, being part of the original DC would be good, too! Might attract more interested players!)
But about more releases/updates - great! Always looking forward to that
