OK, I know I'm going to get stomped on this one but this topic is to revist Mech play vs Protoss. I am a high master Terran who has tanked his account to learn new mech builds and some have actually worked; I think it needs refining.
I feel this matchup is relatively unexplored - and the common answer is because "TvP mech Sucks". I refuse to believe this mentality - I just think it is more challenging than bio. Day9 did a show in January on it but, other than that, the build (or even attempt) for players to duplicate this on ladder is uncommon.
Recently a old style with some twists of using Thors/Cloak Banshees/Marines/Raven (1) with a scv push as emerged - Boxer used this in the last GSL (but lost). This is obviously after there is early banshee harass. But I rarely see mass tanks and helions anymore. What I am interested in exploring is perhaps a mech/bio hybrid army. For instance, one of my builds that worked was a early helion drop into expand (this is of course vs standard Toss 3 gate robo expand). Then drop 2 reactor barracks and 3 factories to produce tanks (no stim only combat shields). Then basically push while the colosi count is relatively low; even bunker outside of the protoss base if possible and slow push (similar to bw). As the game gets longer transition into more tanks/thor/emp - no bio upgrade only armory.
I feel Terran has been scared to think outside of the box in late game and simply tries to take the mass Protoss ball head-on, which is very diffcult with just bio and emp (especially after the emp nerf). I think a answer could be a mech/bio composition if transitioned and played correctly.
Obviously I'm a big fan of GoOdy being a mech player and even he has transitioned out of mech (only vs P). But I watch his stream and he still uses it occasionally. After talking to him after one of my showmatches he disclosed the helion nerf was the main reason for his switch. But why cant we replace helions with marines? Or a combo of the two? Remember, I'm exploring mech hybrid or pure mech timings that rely only on the mech upgrade. If bio is used then only combat shield and stim marines.
I would appreciate any Protoss or Terran input. AND ANY TVP MECH REPLAYS - they are so scarce. Thanks community!
Also review this thread: He is also high masters (lynna) and has a great-long game mech/strategy build
PS a 1/1/1 one-base all-in does not count a mech build
Here is the day9 special on TvP mech:
