Indeed, a lot of Zerg strategies are very APM and reflex intensive. Your reflex must be really good in order to win a game. Zerg might be less micro-intensive, but reflex wise I think Zerg is probably the one that needs the fastest reflex.
Do you guys think Zerg is harder to play for beginners? I'm Gold league zerg, but I always find myself losing to high pressure games from Terran/(and sometimes) Toss. When I watch replays, their macro and game sense is terrible, but it seems that their strategies are easier to execute. I'm not saying I'm much better, but I do think that I do a lot of things right, but one wrong decision (like one wave of drones at wrong timing) can just allow the opponent to corner you in, starve you on one/two bases, and win the game.
I don't know, that's just my opinion. Maybe I'm worse than I thought and should focus more on how to deal with early pressures.
Added on December 13, 2011, 2:25 amI think when you go infestor/ling, positioning and timing is really key. Flank is also extremely extremely helpful.
While if you go for muta/blings, more focus on harassing to keep terran econ down. In major battles, I feel muta/bling is easier, just make sure you split your blings a little, run to the right direction, and make sure mutas don't fly to marines. Whereas for infestor ling, you need to go in at the right moment before the terran split his marines and take center positiion on the map. So you can fungal the marines and the lings can handle the tanks.
actually many protoss and terran player will try to end the game vs zerg when they are on 1 base or 2 base. Terrans especially their MMM are their most trademark and cost effiecient unit they can ever produce. prolonging the game past 2 base will make the game falls in favor to zerg players especially when they get 3 base fully saturated and mining, thats when their macro starts kick in with full force and it become a nightmare for terran and protoss plqayer to dealt with...... no point for us terran to outmacroed a zerg as the mechanics doesnt really allow us to do so. so the only option for terran is to do constant harrass pressure and timing push...
