i think is a good nerf even i am a terran player.
because currently i feel that T when rushes to a siege tank or battle cruiser, then is hard to counter. Yesterday siege tank in siege mode actually choke out all point where my thor and massive army also useless against it.

Guess that's why terran was being nerf so much. Finally now with zealot and reaper being nerf, my mmm will be put to more use, since i basically like MMM much better.

dont flame, just my 2 cents.
