@Ragnarok, sorry buy I don't go with the Self-Moderation idea.
If you are diabetic, you just ask for you folks to not leave a chocolate bar on your bedroom. You do not act like if this would be ok just because you can "Self-Moderate".
A friend of my was recently playing a game WT3, and he complained to me that the game was just to easy... so the solution he had was to play all of it without armor, sacrificing a big part of his immersion to make the gameplay pleasant. Do you think he was ok with that? He wasn't!
It's not the players obligation to "moderate"/"Balance" the game. That is why "difficulties" are implementes as well as "Toggle features" so everyone finds an "reasonable" balance (IF he wan't to), of course, some people just wan't to experience the story.
Adding more on the matter, using Self-Moderation as an argument to not balance something would work on so many aspects that the company could just forfeit this part of the development and just say "Be moderate people".

I dare to presume that is something you dont like ...
Lets presume your suggestion was inplemented, and Hide become an action for everyone, but rogues ...
So the Question is: What exactly is stoping me from creating 4 Custom Rogues party, and exploit it just the same?

Answer is simple: Nothing. And therefore i see no reason in this inplementation, since the problem remains ... it only makes the game more anoying.
This aspect, IMO, it's not about liking or not. I dislike weighted dice, so I just turn it off, and for people that keep it on it not breaking the game, it just change the experience, same as Easy/Normal/Hard effect. This case is completely different, because it does break it.
Make me remember a tactical game of a mutant party that the game was completely unbalanced with only few characters been really good and the others trash. You could play with only one of the spectrum? Yes, but again that is not you job.
About you creating 4 rogues......, yeah, there is nothing stopping you from that but then it just wouldn't be an exploit. It how the class suppose to work and how it is balanced, you're "paying" the price for this in others aspects like social interaction, AoE attacks, versatile etc. The problem is not the feature/possibility of sneaking and then attacking, the problem is making this for everyone, that is "hurting" the rogue in the same way that giving wizards every spell on the game are hurting Clerics/Druids/Warlocks etc.
