Why does Ghost EMP remove Protoss shield AND energy?
Are there any other units in the game who's abilities affect a race as a whole and not just serve as a "counter" to a specific unit/set of units?
I mean, I can think of situations in PvT where there are certain units I just don't build as a result of my opponent's build i.e. if I see mass marine, I am not going to build mass immortal. Aside from the having to allocate resources to build Ghosts (just like every other tech path,) it seems like there's never a PvT where the Terran would suffer from throwing in a few Ghosts into his composition.
Is there ever a reason for Terran to not build Ghosts against Protoss?
