Well, you can frame it as a balance issue, in that if your classes are already balanced arbitrary DM buffs will make them not balanced, and if they aren't balanced arbitrary DM buffs will not fix that because different DM's will give different arbitrary DM buffs when prompted.
But it's also just a simple matter of agency. If you aren't willing to tell everyone what superstrength does up front, then the choice between superstrength and magical underpants is
uninformed, and that is disempowering. I hope we can all agree that hiding the mechanics of the players' abilities from them is bad, and obviously any rule that
hasn't been written yet is hidden from the players.

Okay, this is probably accidental, but it's getting annoying.
Do you notice how you keep switching back and forth between a general discussion about design and specific complaints about 3.5's failings?
Stop doing that. This discussion is system-agnostic. You know it's system-agnostic. Your very next post after this one contains the phrases "the game should support..." and "if the game supports it...", which are not phrases that make sense in the context of discussing the rules as they exist. Because we are not discussing the rules as they exist. We are having a general discussion about "how shit should be," and we are having it in terms of 3.5-like mechanics because, well, D&D is everyone's default for this shit.
Porting in 3.5's balance problems to levy "fighters need all the help they can get" as an argument is just taking a piss on the conversation. I don't think you intend to do that, but you're doing that and you should stop. This isn't the only place where it's happened; you did it multiple times in that post, and again in the next. You're right, fighter shouldn't be a shitty class and it is.
Moving on.

Take the stealth rules and replace them with a bunch of empty page space. Every player at the table will still know how to get better at stealth (increase ranks, increase dex, decrease size). Not a single player at the table will know what the fuck improving stealth does. That's awful. The numbers on a character sheet mean absolutely nothing in a vacuum; they're just symbols. You could replace them with drawings of fruit.
You need actual rules somewhere telling you what you can use those numbers (or fruits) to do, and if your DM is making that up on the spot then it's impossible for the player to know what those ranks are buying them - and it's impossible for the game to be balanced, because the author also doesn't know what the ranks (which have an opportunity cost decided by that author) are buying the player.
deaddmwalking wrote:Saying 'anyone can use grapple in a new way' doesn't inherently favor any specific class - it does favor anyone who has invested in grappling, but that does not make it a 'stealth class feature'.
This is just dumb. "Anyone can add their intelligence modifier to the saving throw DC's (again, if the DC was already int-based) of any of their abilities or spells." Tell me that doesn't favor wizards over fighters in two different ways. I dare you.
Unless you are planning to say that every class is equally capable of investing in grappling (wut), then yes, adding functionality to grappling favors the classes which can or do invest more in grappling. That is really obvious. And yes, some classes are going to be better at grappling than others. In 3.5, that's the wizard, because magic. In 3.5 that wasn't shit, it'd probably be a martial. If giving up magic doesn't make you better at being a martial and doing martial things, why the fuck did you give up magic?

Some characters despite having a rank in the skill don't have a bonus high enough to succeed at a particular task - but eventually they will have a bonus that makes failure impossible. It's the difficulty of the task relative to your ability that matters - really the only thing that matters.
Level 5 rogues don't actually go adventuring with level 15 clerics. The fact that different characters might be able to do the same thing at different levels is... okay. Whatever. Can they do the same thing at the same level, whatever the level may be? No? Then what's your point?
