Yeah, I've also been doing a 2rax expo rax fact -> tank play recently with lots of mauraders vP.
TvT : Herrion tank.
Mech play that's standard these days. From my understanding, a lot of AM players are still pretty bad with this, so getting the hang of this will help u a lot in this matchup. It's not that hard as bio too, imho. Either start with FE, Banshee or BF helions and build 2 more factories later with adding vikings and ravens. U should learn a bit more about this from other players or/and vods.
TvZ : Herrion tank rine, start with reactor helion expand.
U start with 12rax, gas factory, and reactor on rax. Switch it with the factory when it finishes. Pump helions, and build CC after the 2 helions. should be before 5min. Research blue flames and going for drop after bf can hurt the zerg real bad. Pump rines, tanks and helions, obviously Practise running the rines away from banelings, focusing tank fire on banelings. Build turrets at bit after 10 min or when u scan the spire. Against infestor ling play, get faster third, and mix more herrions
TvP : 1/1/1 with the banshee focus variation, without cloak.
rax, gas, factory, reactor, gas, starport with factory techlab switch. Keep pumping banshees, rines and tank. Upgrade seige mode at like 8 min+ and push out at 9-10min with 10+ of ur scvs.
Stick with this, work on ur mechanics, ur masters in no time
