What is the point of having a single stealth preacher ? Stealth preaching has counters and works only with mass of priests anyway. It's not that useful in early game because you don't really have a lot of immortal units. Stealth preaching doesn't really has any other useful side that both of those...

Moving with the scout prophet creates another problem : I may be strange but I use the scout to scout.

Well, as I said, it may have a use... but it is not in my opinion good enough to make it "noob tip".

That's what I would call a noob tip : fill the map with scouts, especially in MP !
