Couple of things.
Well, from a tabletop standpoint it should be either Divination or Necromancy. Seeing how they have destroyed the core of Necro (animate dead), I'd say Divination. Moreover, Wizard played as damage dealer is (and always be) subpar and, regardless, Evocation school was never that good anyway.
That's irrelevant here though.
Larian let you double Fireball with Haste (or "surprise attack") which alone sweeps all balance out the window and makes that the most powerful thing by far that you can do. One-hitting enemies with damage before they even get a turn is a thing in BG3.
They also let you do
double damage with Lightning and Cold spells just by making enemies "Wet" first. Again, ridiculously OP in favor of blasting away.
They also crafted an amulet that pushes Magic Missile damage to be OP. I don't see an amulet that increases your Enchantment spell DC's by +2 or increases your Sleep potency. What I do see is Sleep getting nerfed hard, and Minotaurs completely ignoring my Sleet Storm by making 60ft. jumps over it.
They nerfed all forms of battlefield control magic, as I described in my previous post. See a pattern here by this developer how they (not so subtly) encourage you to play?
So, Evocation is in fact by far the most powerful and nothing else comes even close. I can only hope they pay attention to these forums and see how they're ruining their own game pushing a certain playstyle so hard and eliminating others in the process.
Couple of things.
First of all thank you for updating me on the current state of the game, I didn't realise that Larian had moved even further away from PBH than I previouly knew/imagined. I'm almost disappointed but eh, this is the way the game is going to be, apparently.
Having said that, with reference to the matter at hand, almost everything you stated does not really matter with the Evocation school; you can do everything you listed as AnySubclass-Wizard.
The +5 damage "capstone" (since it's the last perk an Evocation Wizard is going to obtain) is, while not negligible with some spells (e.g. scorching ray), not really impactful (unless they changed more). I'd rather secure an hit with Disintegrate or save any of my char from a save or suck spell (potentially causing you to lose the battle) than having my spell do +5 damage flat.
Well, you can argue that the best perks an Evocation Wizard can offer is Sculpt Spells but i learned from experience that it rarely comes handy. Again, unless there are even more changes that I am not aware of, I'd pick Divination over Evocation all day every day (for the above mentioned reasons, and more).
Unless your post was just to explain that Wizard can be treated as a proper damage dealer in BG3, in which case, again, thank for the update (unironically).
