Yeah you better check how pros are actually using stalkers.
Blinking and picking up SMALLER groups. Just check what happened when tester blinked up stc's main for the 2nd time; he was forced to retreat to what seems like an equal or smaller army even!

Stalkers have a niche, ranged weak dps with a lot of mobility. If you think they can form the backbone of your army, you're going to lose to the basic MM again and again.
Remember that this discussion started because you think protoss vs Maru aggression, zealots are not needed. Think again. Marus cream Stalkers, and they're actually cheaper even.

Did tester outproduced stc? Hardly. The stargate was idle midgame onwards and it's difficult to say that the VR did enough damage to justify the tech. The DT shrine hardly paid for itself. The DT didn't do much damage. HTs could have changed it all but they came too late. All the while stc only made MMM. Solid MMM. Tester didn't have a larger army to deal with the MMM, and was slow on the tech (HTs).

What's your IGN anyway?
