Ah, sorry, I'd have combined these posts but it was on the next page
So...you need to remake your character and it's no longer compatible with these rules, right?
Why are you remaking your character? Generally you would make a new character, not remake an old.
But, by this definition, any character with alert if no longer compatible, because alert USED to be a +5 and now it is +prof. But that isn't incompatibility, that's the rules changing. And if you want to complain that any rule changing makes it incompatible... you are going to have a bad time in the future.
This isn't a "rules problem" this is a "rules change" just like Dwarves getting tremorsense and high elves getting misty step.
Granted. I can only analyze what they put out.
Sure, but you seem to want to go from "if they keep this rule, they will need to change more things or have abilities that no longer work" to "These abilities are going to be worthless when they publish these rules they are guaranteed to publish!"
They don't even know if they are going to go with this rule, and pointing out the things that it doesn't work with is helpful. Declaring they have lied and the game is broken and many books need reprinted because of this rule is not helpful.
Yes, not too hard a fix. Will they issue errata?
Probably. Don't see why they wouldn't.
It's going to require a lot of updates, and it's unclear they will update non-core books.
No it won't.
Again, you seem to be confused about this. In Tasha's they released the Beast Barbarian which has Infectious Fury which recharges on PB times per day. They also released the Order domain which had Embodiment of Law which refreshes on Wis Mod per day. And both of these are compatible with playing a 2014 Dragonborn whose breath weapon is once per short rest.
They CAN update things to make similar abilities recharge at similar rates. It would consolidate design to be sure. But it isn't required, it hasn't been required for any of the PB per Long rest abilities released over the past two years. There is no reason to assume it is suddenly required now.
Every feat needs an update, in the very least giving it a feat level.
All the feats. All of them.
Every feat in all those books needs updating.
Not worth an errata (are there even any feats in the SCAG? Oh, the Deep Gnome feat. Already worthless since the Monsters of the Multiverse release)
Just assume any feat that doesn't have a level is a level 4 feat. I mean, if you need official word from Wizards, they can literally just add that sentence into the PHB. There is no reason to reprint entire books just to list levels by feats.
Also, I want to note. None of your previous objections (the four I listed) included "they are giving levels to feats so they need to reprint every feat in the game". So, we are up to five objections and only two of them have any real merit it seems, one of which is a simple fix and the other which is a legitimate concern.
