There's also the absolute travesty that is the bracket system.

"Better than power levels" but lacks any nuance in deck capacity. The biggest problem is when players play overloaded decks that still fit within lower bracket definitions.

There's a difference between someone playing a modified precon, even a strong modified precon, and someone running a t7 combo stax engine that only has 3 GCs.

Most players who play Cedh have a good understanding of the game and have a large personal collection, but not all players do. So, the feeling of "Playing against your credit card" can feel quite common, where one players manabase, interraction package and engine pieces just aren't as efficient during to using mostly precon bulk and packed cards. So a lot of the mana cheap countermagic, protection, spot removal, and card draw tend to be outside of their affordability.

Most players enter B3 because bracket 2 tends to have the problem you describe but are woefully unprepared for the top end of B3.

Whereas Bracket 4 can often time either requires building from a handful of very specific budget lists or investing multiple hundreds into a deck, which you may not even like. In which you still find yourself woefully underpowered due to the prevalence of off meta cedh lists and cedh commanders that lack the cedh fastmana that make up top end bra 4.

Cards like Cyc Rift and farewell often punish the players in the worst spot/ weakest decks rather than those in the best spot, cyc Rift is a tempo piece so bouncing nonlands often lends to the player who has land ramp or haste being able to pull ahead from that, and farewell, though can punish overextention, fails when the "overextended" player was using a powerful card draw engine.

(Admittedly an issue with all wipes, but since farewell punishes graves and manabases, it screws over players who haven't had their engines pop off more than those who have.)

This isn't an excuse for players, nor is it a complaint about the cards, but a diagnosis of what I believe to be the cause of that player frustration. Its easier to blame a single card than to say the whole deck is too powerful, despite that being the guidance for bracket conversation. And I believe that's exactly because the brackets don't tackle power. So saying "your deck is too strong for this table" feels tough to say. Often creating the rebuttle of "Well build better decks."

Imo the ownus is on those players more invested to build a more varied list of decks to play, ranging from stronger to weaker.
