I'm learning from my mistakes! So I had a TvP (which is supposed to be a good matchup for me) earlier where I went m/m/m but emphasis on the first m and got roasted by like 3 colossi at his base; it didn't help that I had my units try to target the colossi like a tard, when a lot of them couldn't get in range, but it feels kinda damned if you do damned if you don't in those battles - like, what are you gonna do, sit back and focus on units in the front and let colossi fry you? Sigh.
So, got another TvP just now so I decided to go m/m/m with emphasis on the second m (marauders! went 6 rax, 4 tech/2 reactor) and it worked out muuuuuuch better. He went with a composition of gateway units/colossi with a few void rays mixed in; in the first battle we fought, I had no vikings (I didn't scout his colossi at all, I scanned his front and saw gateway units with a couple void rays...oh, wait, I guess I should have made vikings anyway for the void rays! lol me), but I did okay in the fight (traded roughly even supply, he did slightly better) and retreated to my base. Fight #2, we're both maxed, he has 5 colossi and 6 void rays for my 10 vikings to deal with...yeah prob should have brought more. My 3/3 marauders are straight BEASTLY though (he has 2/1/1 lol) and tear through his ground army, but my vikings are taken out by the void rays and I have to retreat once all his ground forces are dead. Also he's on like 5 bases right now to my 3, and is up 30 supply despite having a smaller army than me based only on workers.
We remax, and this time I'm up to 12 vikings, but he's also up to 12 void rays and 4 colossi. It actually might have gone much differently if he focused down my vikings with his void rays, but he spent too much time firing at my ground units and so once my vikings cleaned up the colossi they took down the remaining void rays pretty easily. In desperation he warps in a round of dark templar, but I figure out they're there pretty quick and take them out after a scan. With his army supply down to 11, he quits!
Lategame TvP and dealing with colossi in general def feels like a leak for me, it feels good to win one.
Here's the replay if anyone feels like seeing what the better end of a goofyballer SC2 game looks like these days. And trust me, it's still super ugly - I have no idea what "establishing map control" is, I don't scout his 4th or 5th bases ever, it takes me way too long to put my own 3rd and 4th up despite facing no pressure or resistance, I do a very poor job of scouting his tech (my scouting vs P is basically to figure out, "is he 4-gating?"), I forget to build units during battles. On the bright side, I did well with upgrades and didn't let my bank get to epically awful proportions (it got high a couple times, but I did wind up spending it all so I guess it was good to have).
Bonus replay: When 4-gating PvZ goes terribly wrong, drags out into a 20 minute game, and still results in this:
