Might be just me, but I don't like characters that are build soley on primary attributes, so I actually really like that those proficiencies go on intelligence. I usually spread the proficiencies a bit based on the background and not attributes. It feels a lot more natural to me (but I'm also the guy that always has his rangers with higher intelligence attributes than constitution).
I must admit though I miss the favoured enemy doing additional damage. Was it 3.5e and Pathfinder? For me the subclasses are the actual problem with the ranger. I would love to see the new Beast Master from Tasha's Cauldron and Gloom Stalker (as perfectly fitting for an Underdark campaign) implemented. But besides that I really like Larian's adjustments.
