There is nothing wrong about maxing the character as long as it's legit and do not totally break the system.
If someone enjoy it, why not? For me, as a Game Master it's not a problem. Also, I can help optimize the character of weaker player if it is needed.
In other hand: I never liked poseurs who think that making character strong is "not rpg like". I met some of those guys before and they were nothing more than a burden for a party. Want to create a character with weird stats or feats? No problem as long that character is useful and carry in something to the party. Except moaning, of course.
