Have many of you used it?
Is it better than the old builder?
i would guess so since the old builder seemed clunky.
i was just wondering, and I would like to hear.
AFAIK it still uses the old pre-MM3 math for everything.
This may have changed since I let my sub lapse, but I haven't heard anything to that effect.
WOTC has stated that they currently have no plans to update monsters from MM1 and MM2 to the new MM3 math.
So dont expect it when you use the Monster Builder.
