So is the expectation that in the next edition a player should be able to call upon any of the six abilities in any given situation? That seems like quite a stretch to me.
Yes, this appears to be what the OP is saying. My response can be summed up as: So what? Why is this a problem?
Ok, have in mind I don't mean the concept of "balance" or "so and class will be overpowered", but consider this. If you're having a system closely linked to ability checks it doesn't make much sense to include an ability that's useless for making checks and is virtually just a combat stat. I think it's akward when the system starts with five abilities that are good for combat and good for non combat, and one that's good for combat and virtually useless outside of it. Not because it's any problem, but because it feels inelegant, a weird chimera of new idea and old sacred cow.
I killed your master, and now you die as well. Clearly I was referring to a dwarven fighter-thief.Hmmm...... your AD&D kung -fu has grown weak. Any non-fighter class gets a max of +2 hp from a CON of 16 +.
I would houserule otherwise.
Inelegant - perhaps so. However, over-focusing on elegance can lead to a bland system in which everything feels like everything else. In fact, I think this was one of the problems with early 4E.
I'm not saying elegance should never be a concern, but in general it should serve the larger goal of making the system easier to learn and/or play. I don't think "all stats have an active use" is particularly important in that regard. (I found it quite irritating when 4E tried to give Constitution an active use by shoehorning it in as the Infernolock's attack stat. Yeah, my character uses her healthiness to burn your face off. What, is my warlock pact with Jillian Michaels? I'm not saying Con can't be important for the Infernolock, but it should be used to resist nasty side effects, not for direct attack purposes.)
Also, Constitution is useful in exploration as well as combat; anything that puts you in physical danger (falling off a cliff, springing a trap on yourself, being caught in a rockslide, etc.) brings in Constitution. A social encounter is the only situation where Con is really useless, and the same could be said of Str and Dex. Meanwhile, what good is Charisma in either combat or exploration?

Rather than ditch Con, I'd reinterpret it to mean vigor, energy, and mettle. People with high Con are hard to keep down - either they just have a great amount of physical vitality, or they have zeal and drive to complete a task. I would have Con be the go-to ability for athletics, fighting spirit, valor, and presence. All these things require vitality and a will to endure. Placing them under Con's aegis would help make Con seem more active.It's a sacred cow, they want to include everything D&Dish in 5E, so they won't get rid of Con, but if they were willing to make a good change for the system, I would ditch Con and have only 5 stats, or find another physical stat that is more proactive, or combine Int and WIs into a single stat while ditching Con to preserve the physical/mental balance of stats.
You don't drink your diplomatic opponents under the table?
