Just Want Honest Opinion from this

Never ran any campaing with these, and I am planning to run one as a GM and it will be the first time I have Homebrews that ban/remove stuff rather than add/buff stuff. It is a new thing I want to try out.

Could you please provide honest feedback about these:

Banned for Crafting:

• Ring
• Rod
• Scroll
• Staff
• Wand
• Wondrous Item
• Enspelled Weapons, Items & Armor

Banned Items:

• Magic weapons work like Thor’s Hammer, if you do not have enough dedication to the ways of the sword you cannot use it
• All Weapon & Armor for Wizards, Bards, Clerics, Druids, Warlocks, Sorcerer
• Rare, Very Rare and Legendary Weapon & Armor for Paladins, Rangers
• Magic Armor with +3 bonus

Circle Spells:

• Banned

Banned Spells:

• Hypnotic Pattern
• Shield
• Forcecage
• Simulacrum
• Mordenkainen’s Magnificent Mansion
• Demiplane
• Leomund’s Tiny Hut
• Etherealness
• Wall of Force
• Banishment
• Forbiddance
• Nystul’s Magic Aura
• Polymorph
• Mordenkainen's Private Sanctum

Summon Nerfs:

• Total HP halved,  all positive modifiers halved, damage halved (stacks with modifier halved)

Nerfed Spells:

• Phantom Steed: only 1
• Suggestion & Mass Suggestion: needs to be reasonable
• Rope Trick: takes 10 minutes to cast
• Planar Ally & Planar Binding: follow summon nerfs and requires concentration
• Silvery Barbs: creature makes Wisdom save, if succeeds does not impose disadvantage

Spell & Abilities with long lasting effect:

• DC gets a -4 for the next turn after a second failed attempt, stacks 

Potion Nerfs

• Drink an amount bigger than your Constitution modifier, gets one level of Exhaustion per potion as your body is overwhelmed with the magic
• Healing potions are the exception to this rule, as their healing properties nullify that effect

Natural Flight

• Needs to use the Take Off action. 
• Requires concentration. If you lose concentration, you fall 600 ft.
• Disadvantage on attack and Stealth rolls while flying.

Extra rules:

• Can use movement + bonus action to perform a Skill check action to do something
• XP to next level is your level +3, which is the number of Meaningful Encounters you must beat
• The DM decides what is a Meaningful Encounter
• Bounded accuracy:
  • Before 10th level: rolling 10 or less = commoner. rolling 20 or more = skilled
  • After level 10th level: rolling 10 or less = skilled. rolling 20 or more = peak, expert, master

Why can't Palis and Rangers get cool magic items? Paladins have A LOT of very rare and legendary weapons SPECIFICALLY FOR THEM. Debuff spells are not that broken. It's already pretty likely that a creature will save on the first or second repeat save. You should nerf, not ban, the powerful spells. You banned Shield but not Silvery Bars?

Hi, thank you for your answer. I will provide my reasoning, you can tell me if it is wrong.

1. Paladins do not need the Holy Avanger because it is already in them. They can smite, and have holy aura. 2d6 vicious weapons + smites + spells with Paladin is very overtuned. Fighters do not scale, and need the damage much more. That balances the Paladin and buffs weaker classes.
2. They are not broken, but they can be with combos, and most of them are overtuned anyway despite not being flat out broken.
3. Maze requires a 20 Intelligence check to escape. Tarrasques have -4 on Intelligence, meaning it is impossible to escape. That is a broken aspect of the game. Plus, often some characters have +0 on saves at high level, and with DCs of 20+ they are expected to be banished from playing entirely which is not fun.
4. I tried nerfing spells before, but players did not like many pages long of homebrew, and with how it is I can fit it all in one page. Plus, some needed nerfs change the core way these spells work, meaning what you are doing in practice is removing a spell and adding another one with the same name. Banning is just cleaner and simpler.
5. Shield is OP. Even +2 AC as reaction for a whole round is really overtuned for 1st level. You either butcher it or remove a core trait like slot level. On a second thought, Silvery Bars can be equally spammed at high-level. So you are right, if Shield was banned, Silvery Bars may also be.

I would not want to play with any of these limitations, let alone all of them. It seems like it would suck all the fun out of the game for no good reason.

Bladesingers, swords bards, war clerics, and bladelocks just don't get anything.

What is your reasoning behind doing all of this banning?

Hopefully making the CR system work better and monster do not insta die and there is no imbalance on the team that requires me to homebrew magic weapons.

To be brutally honest, this kinda feels like your car got dinged in a parking lot and you felt the best way to fix it was to drive the car into a lake.

What level are you starting the campaign at?

The CR system is always going to be a 'guideline' at best. Certain parties will always do better against certain monsters/encounters, and worse against others.

Also, the CR System is entirely superfluous. You can run a complete campaign without ever using it. And you are breaking a host of other systems in order to get that one unnecessary system to work.
