[Protoss] Opening Zel+Stalker or 2x Stalker

  (Edited: )

Hey Everyone,

When I roll Protoss i normally go for some 2x Stalker harass which works well for me (gives time to react or expand), I was just wondering why players go Zealot + Stalker instead of 2x stalker as it is obviously better. I seem to recall Day[9] saying something about the Zealot being a requirement to stop some kind of rush? Can anyone fill me in on why the Zealot is made. (I find it too hard to kill the scout with just Zealot.)

I am looking at doing a Stalker + MCore harass as it will beat anything except an equal amount of stalkers and just want my bases covered.
