Now actually trying to play a character concept, that's more difficult.
This reminds me the larping thread.
Someone would say that they would pick even worthless/mostly useless skills if only to be consistent with a character concept, calling it roleplaying.
Another person would accuse larping on sole grounds that he knows those skills are useless and don't affect the game at all.
And both would be right, creating and developing a character following a concept is roleplaying, but when the game fails to give you
some bang for your buck, or at least adequately react to those choices, then you're larping, that is roleplaying without a connection with the game - a less than ideal situation.
Essentially, I'm arguing that giving every skill
\o\o\some/o/o/* spotlight reduces larping. It would be like a magical world where Skyrim is 2 thirds its size and more adequately reacts to the player's choices.
Furthermore, allowing every choice at character creation being useful is in line with the Infinity Engine games. True, its not like most of them had skills, but you had to actually make an effort to create a useless character, or even party.
*Read: you don't actually win the game in character creation: skills may at times make some combat encounters easier, or sometimes allow you to avoid combat, but never the entire game. I doubt they even have the resources for that.
