I don't know why you would assume 5e is not for me - I have been enjoying it as a player and a DM. But this is not about 5e, this is about BG3.
I think you are missing my point. In 5e most of the joy doesn't necessarily come from combat, but from the roleplay. The rogue will shine if your party is breaking into a dungeon, scouting ahead, stealing from npc's. But in combat you pretty much do one thing - you set up and execute Sneak Attacks.
BG3 exploration and social interactions are scaled down compared to 5e. I am sure you can't deny that. Most of the time you will be fighting.
And if during the first chapter of the game the rogue's key feature brings very little to the table, then why play it. That is the point I am trying to make.
I feel like tweaking the enemies is the simplest solution. If every goblin you faced in EA was a 7 HP 15 AC goblin then the game would quickly become incredibly boring and frustrating for classes that focus on hitting AC. Which at the moment comprise 4/6 classes in EA. I include Warlock in this because most of your time you will be using Eldrich Blast for damage output.
Which is why Larian scales goblin AC - they seem to have AC 9-14 from what I saw. Which I think is a perfectly fine approach.
Because you think Rogue's only purpose in combat is to be a Sneak Attack generator?
Remove all of the stupidly added Bonus Actions everyone gets and see how much more useful Rogue's become in combat beyond just Sneak Attacking.
The easiest solution? Start from the rules of 5e and tweak as needed. Stop thinking that every individual character needs to be able to be the star of every single combat. Stop thinking that having 1 character miss or do little to no damage in a fight must be avoided at all cost. Realize that the player controls a *party*. So yeah, in one fight the Fighter gets to GWM the boss into oblivion while the Cleric is just casting buff spells. Maybe the next combat is against Shadows so the Fighter is just swinging wildly, doing little, but helping keep the enemy in place for the Cleric to drop a big Turn Undead.
Seriously, realize that "It isn't fun to miss, so we need to make it so players don't feel bad" is wrong, and so many problems go away. Larian then gets to take advantage of 6+ years of play testing, for free, and can focus resources on the already identified weak points. BG 1 and BG 2 lasted for over 2 decades, longer than some people playing BG 3 have even been alive, and still are constantly topping "best RPGs of all time" lists. Follow their example, trust in the rules of 5e.
