I just got the beta the other day, and while I have experience with RTSs, the unit and counters in SC2 are new to me. I hope you can enlighten me a bit... 1) As Protoss, I often find myself in doubt of what units to build when. Mostly Sentries vs Stalkers confuse me. Both attack air and ground. But sentries has FF and other spells. So that is always nice! But they also seem more fragile. But which of them is better vs air and ground? When would you build what? 2) The same goes for Immortals, when would I throw them into the mix and why? I play vs all races, so I would like to hear what opponent units and situations call for which of these three. The rest of protoss units, I feel I know when to use. Just these three that makes me doubt.
1) The Sentry and Stalker may look similar, but some factors, do as you say, make them different. Sentries are much more gasheavy, plus having abilites and being more fragile. A good example in the difference is their armor and attack bonuses. Sentries are effective in a zealot mix, as the sentries are gas heavy, while zealots are minerals only. Stalkers, on the other hand are good against for example reapers, banshees and capital air. My advice is, try to get the feel of what you feel counters your opponents units. 2) Immortals are more clear. They only attack ground, and with their amazing bonus against armored are they made to counter high dmg high armor units such as: Roaches, Marauders, Stalkers, Siege Tanks, Thors, Ultralisks and more. They get countered by air units, or small units such as Sentries, Marines, Zerglings and more. Hope that helps!
That makes sense... But as a land army, stalkers themselves are pretty weak, right? I know every unit are kind of, but zealots has a nice punch at least, though they are melee so that might make up for that. Hm. I think I get it...
Stalkers are the basic toss ranged unit. In early game you should protect them behind zealots and make good use of blink, it can be great for taking out mineral lines and escaping on some maps. Sentries are much squishier and are meant to be spellcaster type units. Immortals are toss heavy infantry and are good against high-damage units like Thor, because while their shield is up they can't take more than 10 damage per hit.
