Besides the whole porc thing... how did I actually manage to win this game?
I watched the whole replay and DF had an upper hand the entire time or was at least even.

Even according to the graphs I had less units and less porc as well. How did I manage to actually pull trough to the point where I could reclaim safely and actually managed to get an advantage over him.

Still I can't seem to find a reason to how did I manage to drive him from in front of my cloaky factory to his side of the map even though he had more units and even more attrition rate.

Well, you started Gunships. The Blastwings were good. Your comm was idle for a bit at the start. You don't really need defenses if you make Harpy vs Glaive and have some radar.

Your cloakyfac switch was quite well timed. For a minute or so it looked like you had screwed up your economy but not making either units or a Wasp. But it turned out that you floated just enough metal to make the factory. It looked like a build.

At around ~6 minutes your factories were idle in a non-buildlike way. I am personally disappointed that you didn't Reaver drop, but that is simply because you had the required factories.

The commander pickoff was good and important. I don't think you were using Locust correctly, but I don't really know how to use them correctly. I think Harpy would have been a better choice as they destroy Glaive, Ronin and Reaver.

At ~11 minutes you were looking behind on territory but had a nice nest in the center of the map. A Ronin ball prior to this point may have been good, so you could break through the light defenses on the nearby expansion and capture it quickly.

Your factories kept being left idle. At ~13 you had excessed 500 metal and had 1500 in storage.

DeinFreund seemed much better at using and retaining their army. They built Reavers while you seemed to want to use Locust as a frontline unit. Did you ever make Reaver? Make Reaver and put them in transports.

By ~16 DeinFreund has had the bottom right expansion for free, completely unmolested, with a mere 380 metal in defenses. A cloaky army of around 600 metal could have swept through and killed this any time in the last 8 minutes. Eight Locusts may even have been capable. You being are kept in the game economically by reclaim and commander income.

Note for DeinFreund: Why are you using Impaler against the Stinger first? Orfelius has a dozen Pickets and LLTs and they cannot be repaired against Impaler. Kill those and the HLT is very assaultable.

Around ~20 you finally get a decent number of Locust and start raiding. The nest in the center of the map is paying off as it has generated a lot of reclaim.

I didn't Reaver drop because when I was on my side of the map I was kind of fighting for my life and couldn't manage to do it. Later I was also expecting some AA or DF's Reavers capable of defending easily against my own drops. But yeah I probably could've done it once I secured a significant portion of the reclaim field.

The SE expansion was untouched because I was very focused on taking the reclaim field at the time and the game ended before I managed to send my force down there. In retrospect I should've sent a singular hammer just to remove that expansion or perhaps a couple of Reavers just like DF did to my expansion NW.
