Lot of great news, particularly glad to hear about:
-Spell cast speed determined by wisdom: very nice, sounds like two problems just got fixed at once (lack of use for wisdom+too many spells per combat turn), if the balance works out right.
-Spell power scaling with shards you control, yes yes! Suggested this once or twice myself (as did many others I'm sure, just glad to see it happen).
-Recruiting new races through diplomacy - awesome, practical benefits to diplomacy! Now if you can buy them over with diplomatic capital, or use DC to train the units, it'll be even better, but either way can't wait to see how this plays out.
Question for Stardockians, now that the 'public beta phase' is over - how much influence did the beta testers have on all these great Beta 4 -> 5 changes? I know I recognize several tester recommendations on the list, curious how much more of our feedback is included amongst the "too many changes to list."
