I never said that they would be as effective as a uber character with 18's. Planning and playing smart can make a average character more effective. I've said it before it will be harder but not impossible. It's like a low level game verse a high level game; a campaign with low to average character stats is going to have to played differently then one with high character stats. But it doesn't make the low character stat game any less heroic.
Planning and playing smart can only do so much. A wizard with a 9 intelligence can't cast 1st level spells. Period. He can have the best of intentions. He can "feel" heroic. Maybe he's even a likeable guy.
But a fun character to play? No. Not unless you're playing in a 1-shot for comic relief purposes.
On a side note, I'd completely forgotten that older editions of the game actually penalized your ability to gain experience if you had low key stats:

It is inescapable that heroism involves challenge, and challenge requires the possibility of success. Stats affect your ability to succeed.
A fighter has to be able to hit things, and do damage.
A cleric or wizard must be able to cast spells, and requires certain stats in order to do so.
A rogue must be able to utilize his skills, and depending on his stats, may or may not succeed.
If you can't do those things, then the game will feel less heroic.
It's nice to spout platitudes like "Stats do not make a character heroic" and "Being effective and being a hero are not the same thing" but there is a connection between those nasty numbers on the character sheet, and the heroism your character can accomplish.
And good intentions can't entirely make up for that.
