It's been a long journey!

Double unit production. anyone remember that? that's out of teh game right?

Huh? Are you talking about reactors or something else? As far as I know that is still in, but I get the impression I'm missing some sarcasm/inside joke about something earlier.

As far as I know that's still possible with a reactor add-on (it was still in at Blizzcon '09).

[DemolitionSquid]

Barracks, Factories and Starports all share two add-on's now. The Tech Lab and the Reactor. The tech Lab allows the production of advanced units. The reactor lets a single Barracks, Factory, or Starport build two Marines, Hellions, Vikings, or Medevacs at the same time. This is still in the game and has never changed.

So the only factory unit that can be made with a reactor is the Hellion? Why would anyone want to double pump Hellions?

Critical mass?

Why wouldn't you want to double-pump Hellions if you could? =S

To counter Zergling hordes created by Spawn Larva.

hellion speed make them amazing micro harrassers early game on main economies and early natural expansions

So you guys would make a reactor for a Factory instead of making Factories with tech labs, at any point in the game?

It's too early to answer that exact question based on our limited knowledge of the game.

However, if there is any "mech" build that focuses on factory production/upgrades, then hellions are an important mineral sink for complimenting your army.

The question is "are hellions adequate support units in your standard army?" If the answer to that is yes then the answer to your question is also yes.

It's like in TvP where a player might have 4 factories with no add-ons and 2 factoriess with add-ons. The first 4 are dedicated to vulture production and the last 2 are for tanks. Now a terran can accomplish the same with 4 factories instead of 6 if there's a match-up where similar mech strengths apply.
