I'm a former 2010 Diamond 1v1 player for the protoss in the top 5 I believe. I did this using Protoss All-In. I'm just good with Micro-ing my Stalkers because I played Warcraft 3 TFT as well and have the fiends.
I tried other strategies that Stats does such as Phoenix and Adepts and Immortal Adept Drops and all the fancy stuff.
I just decided that I'm not pro enough to play with Multi-tasking since I got ADHD and get distracted and I'm better at Micro with a high APM avg 300 and 400-600 Peak.
Is it wise to play Stalkers All In until I reach Diamond then switch strategy such as a standard build of adepts and phoenixs or stalkers, sentry, immortals and robo collosus build?
Or should I practice going the build I'm going to do once in Masters level?
