For the Protoss you can always go High Templar and storm worker lines in shuttles. Such a good tactic. Storm was always good on maps like fastest where you have something like 40+ workers mining stacked minerals in the space of only 1 mineral so it's easy to land the storm and kill so many at a time. Storm drops can be good against all 3 races I think, but I mostly only ever see them in PvZ for good reason.
Another tactic that I've thought of but never executed is having 4 DT's in a shuttle in PvT. What you do is you unload the DTs while the Terran is moving out and then you pick up the DT's right when a scan is laid out. You do it constantly hoping the Terran runs out of energy on his scanners. Beautiful, just beautiful idea. I'm not sure if that would work though.
I just played a few games as Terran tonight. It rekindled old ideas of going SK Terran against Protoss. Imaginative, but probably not feasible. It's the perfect idea though when you think about it. Zealots and dragoons are ineffective against mass marine medic, and you get a ton of Science Vessels so you can EMP the High Templar forever while erasing the shields of the main army.
I actually tried that strategy once in a TvP. It was pretty long too. As you can imagine it was a low level game. D+ maybe? My ultimate marine medic drops had a somewhat minimal success rate and HT storms gobbled up countless marine medic balls of awesomeness, but the true beauty and OPness behind SK Terran are the unlimited amounts of Science Vessels. Bunkers always sounded fun to use more just like you would in single player campaign. Nukes. Nukes too. Think about all of the lockdowns, optical flares to blind observers, and all of the almighty nukes+EMP tag teams you can do to 1 shot Nexi(plural form of Nexus).
However, I was not fast enough to EMP the HT before they stormed my Science Vessels. I tried to do the shift click trick where you have 12 groups of Science Vessels, you assign all of them to EMP something, shift click 1 unit cancelling them from the group, and then assign another location/unit for the group of 11 science vessels to EMP and you continue in this fashion for maximum surface area. However this strategy requires the use of comsat scans so you know where you're going to be EMPing. This was always the tricky part. The comsat scans never lasted long enough for you to shift click or "mirror" properly. Several Science Vessels were left with 250 energy that game....
This strategy is much more executable for the Zerg when you're using Queens. The neat thing with Queens is the parasite ability which gives you that indefinite amount of vision you need to do the shift click ability to broodling 12 units. Make your opponents think you hack, and apply a grin on your face. I've seen this used in Zerg vs. Terran mech for heavily defended tank positions. Always a pain to deal with Terran mech as a Zerg player myself. Those spider mines.....those Tanks. I just don't have the Defiler micro or macro with Lurkers/Swarm to properly whittle down the Terran army and defend properly.
I've always been really bad at TvP. That's why I've been thinking about going Terran mech against Zerg as a staple so I fully get used to mech plays more often. I've been partly inspired by watching avilo's stream who always uses mech style whether it be zerg, terran, or protoss.
Watching avilo's stream brings back memories of a good Terran player who I'd observe in play/obs games. One of his defining styles was always going mech vs. Zerg. The funny thing was his bionic play was more terrible than terrible....It was just really bad. Marines and medics would be lined up neatly as possible just for the Lurkers' convenience and so many times would the marines and medics blindly charge into an open field only to be impaled so suddenly by spines lurking beneath.
Until next time. Maybe I won't switch back to Zerg and I'll stick with Terran, or maybe I will. Most likely I will end up going back to Zerg like I always do after a frustrating night of losing to Zealot drops, fast DT's, Reaver drops, speedlots, and Arbiter recalls. I can already hear the Terran race calling to me.
Update: I was right. The Zerg swarm calls for aspiring leaders and I shall join their ranks! For the swarm! This decision was made shortly after getting destroyed in a game of Micro Tournament. Such a shame.
