in case you were not aware, protoss is ripping everyone's ass hardcore in GSL.

right now at this moment, 4 protoss is in gsl round of 8. the highest of all race.

immortal range buff blend a bit too well with forcefield and the cheap upgrade cost make late game protoss ball reach earlier.

So much truth there...
Back to this new patch though, I don't think giving the Phoenix +2 range is gonna make the game balanced when it's against a Mutalisk ball.. I think +1 would make it more viable because as it is, the Phoenix already out ranges the Muta and the movement speed is also faster.. 4-5 Phoenix will be enough to stop the Zerg from using Muta properly.. Any sort of input would be nice
