I agreed, that the changes are ok with bosses like Auntie Ethel (who is so far my favorite encounter) or the spider matriarch. But I, too, would like to see the normal enemies more attuned to their pen & paper counterparts. I find it strange, that my character should be able at level 2 to fight three intellect devourers. Or that the phase spiders jump around and then attack you with ranged attacks.
So I threw my voice in for more true to d&d 5 ruleset stats for enemies.
