Where's that post by Ghostcrawler about how he bemoans people playing for efficiency over fun... I believe a talent tree can work, but it takes a bit of imagination and practice.
Incidentally, I only ended up using half the new talents on my warlock char. The rest are obviously PVP talents (useless to me) or extremely situational. And I hear they're gonna make one of the ones I picked baseline for the class later. So I guess there's not much choice in these new ones either. Either it's a no-brainer because someone "mathed" it out and god forbid you pick a spec that does -0.5% than the optimal build because then you're playing it "wrong", or the talents are basically fluff that gets re-balanced if they're even slightly overpowered and there's no wrong choice anyway. Ho hum.
