I'm watching the replay of your
3v3 on Red Comet and will offer my comments. Note that my Elo is only a little better than yours, so my comments may not be especially insightful (or even correct) but I'll do my best.
1:00 - Great work! You've got raiders out and are attacking with them. Awesome.
1:30-2:00 - Nice job killing the enemy eco, and keeping the raiders on the opposite side of the fac from the enemy commander. Great work there; it paid off with a dead factory, and you even kept your raiders alive.
2:00-2:30 - Looks like you had a hard time dealing with that one enemy Scorcher. Not sure what happened there... It also distracted you from controlling your own raiders, who missed a chance at some easy eco and then got picked off too easily by the enemy LLT and com.
3:00 - You're sending a stream of Rockos off to fight directly into the enemy's base as they're built. Sending a stream of units into battle from your factory one by one is a guaranteed way to lose all your units, one by one. Gather them at a rally point first, then attack as a group.
4:00 - You get a builder out and start expanding. That's good, but you probably should have done this much sooner, either getting out a builder before the Rockos, or just pushing and expanding with your commander. Expansion is victory and the sooner the better.
4:30 - Your Rockos are up against Glaives which is a bad matchup. They're also all on Fight. You might get better results using line moves to micro them more exactly rather than letting them wander around on their own. They're doing okay, but I think that's because Patrician is too busy midfield with his com to effectively micro his Glaives in the south, otherwise he should have slaughtered them.
5:00 - All your combat units are spread out in a long line marching towards the enemy base, thanks to the Fight order from the factory. They're just begging to get picked off one by one. They don't, but I think you just got lucky.
6:00 - Your units are grouped together and able to support each other, they're holding a debris field, you've built some defense (but not huge amounts!) in that area, and have sent a builder to reclaim in it. I like all of that.
6:30 - Now I wish you had three builders so that you could reclaim the debris field much faster. Your com is idle; he could be reclaiming, too. Also, your economy is starting to get out of balance - you need more energy and more buildpower.
6:38 - Uh oh, lost your builder. He was between your units and the enemy; needed to be the other way around. Keep your units close to the front, keep your builders reclaiming in the thickest part of the debris field which is also still protected, which would have been farther south, near the LLTs and Defenders.
6:50 - Uh oh, lost a lot of units by running them in a line forward into a parallel line of Defenders. You needed to pull them back as soon as you hear the missiles fire. You can't attack a line head-on with a line, you have to find a way to flank them.
Which reminds me - you need radar, and lots of it. You should have been able to see what you were charging into, but without radar you ran into a trap.
8:00 - You lost all your Hammers because you didn't have anything protecting them. Artillery needs a safe place to shoot from, and you have to make that safe place with a line of screening units. Otherwise they'll just get mopped up by raiders, just like happened here.
8:30 - Your defense at home saves the day. You lost quite a bit, although you get some reclaim out of it. By this time in the game I would have liked to see either a little more defense in your base (not much! just a little more) OR PREFERABLY a solid control of the forward field. But one or the other. Otherwise you're risking a breakthrough exactly like we just saw. There's no shame in gradually escalating the level of defenses around your base as the game progresses, as long as it matches the developing circumstances in the game.
9:00 - Here come the Ravagers. This looks like gg from here on out.
10:45 - Never give up! That's the spirit!
14:30 - ... but even a good resistance and counterpush is only delaying the inevitable.
16:45 - Good to see the builders come out and start reclaiming, there's tons of metal lying underfoot...
17:00 - ... but it's far too late. GG.
I enjoyed watching the game. You had some good moves in there, and a lot of things you can work on to improve. I hope this helps, although again, take my analysis with a grain of salt. Watch for yourself and see what you think you could do better next time.
