It looks the most recent patch will aid in having the NPC's have a variety of spells, even if their stats do not line up.
But the resetting of talents and other aspects is still rather annoying, especially if you've spent the time to make customized encounters with your players and it's all waste.
I'll be testing my new method this week hopefully, of scaling levels to the sum of the levels of all of the players. Shall update here and let you know whether it worked or failed horribly
