I cant believe im replying to this but here it goes, terran as a race is neither offensive or defensive in nature, if you want to be good offensive it depends on the race of your enemy, their is no such thing as a good stack if a certain race cant be penetrated by it or defend against so correct me if im wrong.
terran against the following
collective= greatly fear P class,zues and thor on agressive murder coll
miner= good ol herc and nirv
maru=p class and queens are good
terran=depends on the player, younger terrans like herc and nirv up front so runners and queens work well, but I pfrefere a more balanced stack and wait for the hit then counter
guard=P class down low in mid stack, herc and tyr up front. good to hit on aggresive but depends on the guard older guards in lower pr use wicked stacks using neutral ships and strafez which = sexy, but all around missle and range is better
viral=since v class has been nerfed tough to say most virals dont spam v class up front unless their lookin for ships, if your hitting a new viral for the first time a 5-6 stack spam might be a good choice to see what method they are using and generaly I dont recomend hitting on carefull with terran unless its a tw stack spamm, I never seemed to do enough damage unless its herc and nirv and I hit fodder or somthing so dont go their, terran ships cant do enough of damage to exceed their own pr
here is a decent typical stack have fun with it and dont ware it out
garuda
herc
queen
zues
c aries
f sword
nirv
tyr
f spear
c cancer
this stack is set up in defence format not realy for hitting
