Consider
@James Gasik's example (
D&D 5E - What is REALLY wrong with the Wizard? (+)). Resilient Sphere doesn't allow the creature inside to be harmed. BUT the DM set up another way for the demon to be defeated by destroying the altar. The spell did precisely what it was meant to do: incapsulate a creature to either protect it or stop it from harming others. Without the altar addition, when the spell ended the battle would have resumed.
You are missing the forest for the trees. You claimed to want "real play experiences" where wizards dominated. You received two, then immediately argued that they didn't
really show that wizards dominated.
Except, yes, sometimes the monster you come up against is a wandering monster and you don't need to kill it, just incapacitate it while you go on your way.
Here's another example of that. Critical Role, 2nd campaign. Party gets attacked by an enormous frost worm type thing as a random encounter. It is absolutely tearing up the party. One cast by polymorph (by the cleric, who got it from their domain), and the frost worm is a CR 0 bunny. Party continues on its way.
Here's yet another example. Wizard first level. Casts Find familiar as a ritual. Doesn't use a spell slot. Chooses Owl, which doesn't provoke opportunity attacks. Every turn in combat, the owl flies to an enemy, uses the Aid action (giving advantage to an attack against the monster) than flies out of range. At the cost of exactly 1 of their 6 spells learned, 0 spell slots and 0 actions, the Wizard is one of the strongest buffers at first level, able to give out advantage once a round.
Also, at that level most demons have magic resistance. So, was it also "bad roll" favoring the players?
A hypnotic pattern has a 50% chance of incapacitating the Nalfeshnee, even with magic resistance. The challenge against a CR 13 monster
with magic resistance is rendered trivial with a 3rd level spell.
Where does the problem lie here then?
The wizard class? Not really, Sorcerers can cast web as well as Wizards, as can Bards via Magical Secrets and certain subclasses gain it as a class spell (Circle of Land - Underdark Druids for instance).
Is it the spell? Maybe. Was the monster Large? Should the spell include advantage for Large and larger creatures? Or should the spell be altered in some other way if it is the problem.
The usual defense against wizards not being overpowered is that their power is limited by their spell slots. As early as mid-levels, this isn't the case for days with fewer encounters. However, even in days with more encounters, the fact that many low-level spells remain extremely powerful (web, hypnotic pattern, invisibility) means that their power isn't substantially limited by their spell slots.
Sorcerers are typically much less effective than wizards for a couple of reasons. First, they draw from a much smaller spell list. Second, their much fewer spells known means choosing to learn Web as their 2nd level spell means giving up many of the other extremely useful 2nd level spells.
A 9th level sorcerer can cast 9 spells, from levels 1 through 5. That averages to 2 spells per level (technically, there are probably a couple they can cast at higher level). They can choose Web and then they need to choose 1 more from Enhance Ability, Hold Person, Invisibility, Misty Step and Suggestion. Those choices have to serve them whether the day is mostly combat, mostly non-combat, and regardless of the monsters fought. Meanwhile, a wizard can switch their loadout depending on whether they anticipate a lot of combat or not.
Was it just "bad rolls"? The monster failed the save, then failed to escape until two rounds later (if I am reading you correctly). Does this mean poor monster design, or do we fault the swingy nature of the d20 itself?
It's not "bad rolls". By level 9 or 10, a wizard's DC is easily 17, and most monsters have at least one save that is only a +0 or +1. A quick lore check (or just common sense), and the wizard can target a defense that the monster has very little chance of succeeding at.
And wizards, unlike sorcerers, can very easily choose spells that target a variety of defenses and still have room in their loadout for defense and utility spells.
A sorcerer could cast web. But an 9th level sorcerer has a total of 10 spells known, compared to a wizard who can prepare 14, plus the ritual spells he can cast from his spellbook that don't count towards the 14.
My point is (as a + thread) about identifying what is really going on when posters say Wizards are a problem, too powerful, etc.
Your first posts above was great, and I even gave one a "like" before I read the last two. But you seem to be more taking issue with my responses than with the issue.
If you are sincere about wanting to learn about others' experiences, listen, and don't try to find reasons why
it isn't really a problem that the Wizard shut down the DM's big set piece because of 1 spell.
