I haven't had a chance to read the whole thread, but I thought I'd contribute:
I am in the SC2 beta. I have been testing it for around 2 weeks now. If anyone has any questions, just ask and I will try and give you the answer to them.
Some Stuff:
- Zerg are crazy.
- Protoss Motherships are a huge pain if you ever meet them.
- Colossus melts mass marines in 2 seconds.
- Reapers are good for harassment, but nobody uses them anymore because they're too slow to build/expensive, and they don't scale well as the game goes on.
- You build nukes out of the ghost academy, not the CC
- MULE is great for gathering minerals, comsat station is a must.
- Thors kind of suck in my experience. They're so big that the enemy just immediately focus fires them, without even thinking about it. No real strengths that I can see, specially since they're ridiculously expensive.
- Vikings aren't as good as they seem. They're pretty weak vs air and ground. Definitely not enough to defeat any kind of mass of air units.
- Ghosts start out with EMP ability, and Snipe.
- Roach rushes are very prevalent right now, so is MMM (marine marauder medivac)
- Marines are useful throughout the majority of the game, they are now the mainstay of the terran army.
- Marauder slowing effect opens up a lot of micro possibilities.
