The Great Con game.

[krud]

The difference between a 10 con and an 18 con at creation is 64Hp at lvl 16.

Again, I never said a melee focused char should not invest in Con.
How many HP you need is dictated by how much damage you intend to take.

But I do think building a char from day one, just to run the same end quest over and over again, is .....well.....not for me. And I run that quest just fine too.

I agree for the most part with your premise. However, nobody is going to make a build where it's a choice between a 10 or 18 con. Typically within the same race and build it is only an option of a point or two of con here or there. For most every build it shouldn't be too difficult to find at least 4 build points to put into con. You'll hardly gimp yourself, and unless you are an elf/drow, you'll start with at least a 12con.
