A few questions I have;

In your opinion what is the best thing to mass, for each race?

For example, in SC1, for me;

zerg; I liked to mass up'd hydras with guardians
toss; up goons, with arbitors and reavers
terran; up'd rines with siege tanks and wraiths

But it seems to me in SC 2 these combos arnt as powerful as they were before.

what are the new combos you guys like.

Hellbats

Looks at me guys, i played SCBW.

and I was horrible at it

Because half the units you mentioned don't exist on sc2 multiplayer.

Reavers and dragoons.. ooh sexy units!and for terran i'd go marine for the way they scream when they die

Tanks.

Tanks beat everything.

air > Tanks :>

make units -> 1-a

No
