They are good abilities, but they aren't indicative of an increase in narrative power, which is what I thought you were getting at? Or is this just one of those situations where you'll decide whether you care about only 5e, only 2e or only the lore based on whether it fits a vague argument against capping the level before 20?
5e is not good as 2e but is not bad. Mainly considering that 5e aims to be accessible as possible and is undeniable a success in that regard.
And I an not suggesting lv cap = 20. I mean, an Elder Brain CR is 14. LV cap = 12/13/14 would be more manageable.
