AngeliusMefyrx, we seem to have completely different views on the worth of Talents. You seem to think that the worth of Talents is ONLY, ONLY the amount of time the player gets to use them, and so you have come to the absurdly bizarre conclusion that players only get to enjoy 3 Talents.
My view, which you completely ignored, is that the worth of Talents is "what is right for my build RIGHT NOW". If a Talent would improve my build, it is absolutely worthwhile, regardless of whether I take it at level 4, level 16, or level 28. The dilemma is not about how much of the game will be left to use the Talent, it is about prioritizing which Talent is most helpful to the build right now, and which one can wait. (This is why I hate the Back-stabber Talent Tax, because it's basically the only answer for a Rogue in character creation.)
That is the reason why you get the Talents spread out over the game and not all at level 1. To force you to prioritize.
