I have just submitted the last spawn overhaul update to Duster, that addresses most of the above concerns since the last update I submitted.
Among other things, the spawn decay times have been reduced, so less time waiting around to see if a spawn drops something or not. Also tweaked the notorious goblin crusaders outside Beregost, so they wont spam spells anymore. Also the fire giant mages will no longer cast a level 9 cold spell.
Personally, this is my last update on working with the spawns. However, feel free to keep posting in this thread if you discover other things and hopefully another dev will get on it when they have time.
