D&D 5E Aberrant Mind's Psionic Sorcery is officially the most powerful feature.

[Hohige]

When you're in a dungeon, with a party, and the denizens are aware a group is raiding the dungeon? You know, like tons of adventures? All this "they don't even know you're casting a spell, OMG!" stuff is very situational. The times that matters are few and far between. So rare most people never took subtle spell. Few care about Careful spell either. Or being a "stealth caster" which is the same point as subtle spell and the same point as being an "assassin" spellcaster - it's all the same highly situational moment and not the bread and butter of most games. And making it harder to counter your spells is good, but counterspell situations are also highly situational.

As expected, the vast majority do not know how to play a sorcerer.

From your opinions, you also don't know how to play the sorcerer.

Again, Psionic Sorcery is cheaper, works as a improved spell point and can still be applied metamagic.
Also, You have no idea of a stealthy spellcasting buffed with metamagic. In a dungeon, attacking without being noticed is just perfect. Play it once and see how it goes.
You probaly dont know How game changer is a Careful Fear or Hypnotic Pattern. No, you certainly dont know.

Remember, you are not a Rogue assassin, you can perform multiple functions and you will never be hit by the enemy or expose youself, It's perfect for an spellcaster.

Repeating, this is cheap, efficient and can still be used with metamagic and can still be casting with you completely hidden.
It also has alot of spells known for versatility and on social roleplay, It god tier.

If you are of the style, fireball and wait for your enemy to hit you. This subclass is not for you.

Heck, isn't there whole swaths of creatures in the game outright immune to mind effects? Like slimes, undead, construct and stuff? What do you do when the Gelatinous Cube riding Clay Golems come for you?!

Not in 5E. Very little (I suspect nothing, but don't want to comb the entire list of monsters to verify) is immune to mind effects generally. There are some critters that are immune to the charmed and/or frightened conditions, but even those are much more limited than in past editions.

Which is not to say the Aberrant Mind is overpowered. It's not. OP has put forward a number of things that are supposedly overpowered, but they all seem to fall into one of three buckets:

a) Features that are good but not overpowered.
b) Features that rarely if ever come into play.
c) A spell in the Player's Handbook is overpowered (hypnotic pattern, simulacrum), or just a train wreck (suggestion), and the Aberrant Mind can cast it.

c) is the only thing that is an actual problem, and it's a problem with those spells, not the Aberrant Mind. If you got rid of the AM, the problem spells would remain.

It takes a standard action to hide in combat and casting a spell (which requires a line of sight) would automatically make you no longer hidden.

Oh right we just don't understand, right?

I don't know why you think his approach to the conversation you're taking is wise, but it's not. It's one of the least persuasive strategies you could choose. Just repeating yourself without discussing points made in dissent of your view persuades nobody of anything.

It isn't an excuse. IT IS A FEATURE. They're not poorly worded because they lack the specificity that you think you want - they're worded to be exactly what they are - intentionally open to interpretation. If you actually understand that, then you won't be tired of the situation.

It's an excuse. There's a difference between being open to interpretation and being obfuscating. Suggestion is the latter, most illusion spells are the former, for exemple.

Also, I think it's a stupid features and why I don't like playing spell casters. (aside from the zappy kind)

Not. Psionic Sorcery doesnt have a verbal component. You remain hidden.
Hidden isnt blinded. You have normal vision.

Let's discuss how truly silly a "subtle spell" fear spell would be. Fear causes creatures to "take the Dash action and move away from you". So they MUST know you cast the spell for it to be of use. It's useless.

Now let's discuss what a "game changer" a Careful Fear spell would be. Fear spell is roughly as good as the Slow spell, which doesn't suffer from issues with targeting allies. Nor are cones all that hard to line up to avoid your allies. I've never heard someone claim the Fear spell would be a "game changer" if it didn't impact allies.

Now let's discuss how truly silly a "subtle spell" hypnotic pattern would be. It creates a flash of a pattern up to ONE HUNDRED AND TWENTY FEET AWAY FROM YOU that "appears for a moment and vanishes". So it already rarely mattered if they knew who cast the spell, and if it did matter you could already try and cast from behind cover and hide because your targets rare saw your tiny hand movement or heard your verbal components. Even in close quarters, it's not like you're wearing armor and it will be hard to figure out who cast that flashy light thing!

So how about Careful spell on hypnotic pattern? Again, I've never heard people complain it causes too much friendly fire. It's not a radius as big as a fireball after all. Not too hard to line it up right.

These are not game changers. They are situational benefits which are nice but not that meaningful to most games.

Hidden isn't only sound based. IF you can see them to get line of sight, then they can likely see you. It's MOSTLY visual based and you're not casting while invisible and silent, you are just not chanting a spell. Your view is not how the game mechanics work for this.

Read rules aboud Stealth.
Be hidden does not give you any conditions and you have normal vision, this is how a assassins knows the direction of his target. Read more about stealth before.
You will be revealed if you make a noise.
With Psionic Sorcery, you remain hidden.

Btw, I don’t know how you guys handle stealth, surprise and being hidden, but in my games a sorcerer trying to scout ahead to get the drop on a group of enemies would probably end up dead very very fast.
