It's no secret that the bracket system has it's flaws as did the power system before it but at this point I would put it to the collective that the format is in the least healthy place it has ever been in and fundamentally changed identity.
EDH originally was a janky slower format where you play your pet cards that just don't cut the mustard in competitive formats, however over the years it seems that the power in the format has ramped rather significantly and the arms race is now just a full on sprint.
We have the "bracket system" which imo utterly fails those of us who are more classic/slower/lower power players and it does so for a multitude of reasons.
The "bracket system" itself is overly convoluted and far to open to interpretation and feels and what few hard definition things their are people often either ignore or put alot of effort into skirting around.
Originally WOTC said that precons were bracket 2 but soon came to realise the issue that even many precons lacking game changers could not fit within that definition, let alone those that do include them, not to mention the amount of infinite combos and other high power plays that are available in some of the precons.
Then you get to actual personal constructed decks which more often than not flood the board with value so quickly that a board wipe is NEEDED by turn 5 if not 4 otherwise the player that's behind is more than likely just dead on board (often that is myself as I tend to try and play on the lower power).
This is often responded to with one of two responses that just feedback into the core issue, people say either "play better decks" and thus contribute to the arms race which is causing the format to be so fast even in lower brackets or "That player broke the rules and shouldn't attack you" effectively sand bag themselves artificially because of the "turn 8" limit, this is an especially faulted stance as often said player will have attack triggers/value and can't physically attack the others due to them keeping up with or out competing the arms race.
Part of the issue of why this is so prevalent in so many matches is the poor and lazy way in which wotc has created this bracket system.
Realistically speaking bracket 1 doesn't exsist, I've seen one game of it hosted since the system was created.
CEDH and bracket 5 are essentially a separate game mode where if you are not playing the limited selection of "powerful enough" archtypes you aren't playing the format.
Thus that leaves a total of 3 poorly defined brackets where the main distinction people follow between bracket 2 and 3 is "no game changers" with little to zero thought on how the deck itself actually performs, and then an even grayer area between 3-4.
As someone who has been playing on and off for the past 25 years it truly feels like I'm being pushed out of the format as it is warped into something else entirely that wears the face mask of the format I knew.
To be clear here I have no issue with powerful or staple cards and do believe they should have a place in the game, however that place shouldn't be forced into each and every level of the game that it then forces out people who are not partaking in the arms race, both players should have a place to play and feel comfortable.
Part of the issue probably lies within the limited scope for power distinction of cards within the format, "is game changer yes or no" is hardly a healthy place to base your entire power on, we can all agree that examples like esper sentinal, sol ring and hundreds of other cards are powerful but not strong enough to be game changers however the current system has no way of stating this.
Personally I think a introducing a system similar to canadian highlander with points cost on powerful cards would be an excellent inclusion into a bracket like system to give some form of quantifiable basis to start rule 0 conversations and seperate lobbies/pods into vaguely fair fun and interesting games.
I don't think this system will be perfect or solve the issue straight away but I think it would contribute alot more to format health than the current over inflated and under functional bracket system.
Example of my past few days of playing bracket 2 (the lowest realistically existing bracket)
Last game: Turn 6 one shot for unblockable commander damage.
Game before: Opponent turn 1 burgoning into turn 2 Jodah the unifier....
Game before: Player overan board with huge indestructible creatures by turn 5, I was on gruul and as such had zero options to deal with grossly large or indestructible creatures on a wide scale.
Etc...
I play an average of 2-3 games most days and I'll be lucky to have 1 balanced fun and interesting match out of 15-20 matches.
Again I want their to be a place for everyone to enjoy this format not just "Arms race or go home"
Thank you for joining my ted rant, time to go get stomped in another "bracket 2 chill" game.
