Nice. If you're putting up 22-3 games, against any kinds of opponents, you're doing pretty well. Don't be so hard on yourself bro.
Don't get too caught up on this. Aiming this high is going to lead you to be real disappointed. You're trying match your level of play to people's highlight reels. It's not a realistic or reasonable goal.
A lot of it is luck. I mean that's the only way you're coming out of it right? The enemy is either terrible, you're engaging multiple enemies but really just one at a time, or you get destroyed. In a fair fight you'll never win a 1v2 or 1v3.
Where are you engaging when this happens? It sounds like you're pushing too far forward. In TDM there are really 3 pushes you can do.
1) You stay in your spawn and anchor the spawn. Low action, low SPM, single people engagements usually. High danger of enemies pushing into your spawn. This usually invovles camping far back or patrolling the back quarter of the map just checking all 3 lanes so you don't get picked off.
2) You push into mid and zone "patrol" the area. This sounds like what you're trying to do. The key here is you never push too far forward because then you put the game into a situation where you're not sure where the enemy is spawning. From this area you really have to keep an eye on radar and use map awareness to figure out which spawn they're on. If your teammtes start spawning in opposite spawn you know you have to face the other direction in mid and vice versa.
3) You push all the way into the enemy spawn and flip it. This is the rusher's game style. In this one you push ALL the way into the enemy spawn and force the enemy to flip to the other side and then you turn around and come back.
It sounds like you're in between 2-3 which is not good. You should really pick one or the other. BTW for instances where enemy is spawning REAL close and travelling together, just be more patient. No need to engage the first guy. Let both run past you and then engage the 2nd guy from behind. If first guy ran too far just run away. Always run away if you're unsure.
RE: BO + BO2 spawns. BO2 had some awful revenge spawns that are worse than anything I've encountered so far. Even worse than this (

Heres a gameplay of me on Evac TDM. Disclaimer: I'm a pretty average player and it was just the first one on my history on evac. but it does show me engaging the enemy spawn a couple times and how I deal with map movement in general. A couple things to note is that it's not the whole match. For some reason it cut off the beginning. I pushed straight into the center and threw a concussion grenade over the left railing then ended up in the stairwell. There was a guy there and when I peek out 5 seconds into the video I absolutely see him but if you lok at the radar there is no teammates anywhere near so I'm uncertain above the LoS up the stairs on the glass room side and through the doors on the west. It's also early match and 3 of my teammates have already respawned on the west which means the enemies are either now behind me or in that room. Not a good engagement.
At 10 seconds I kill a guy in a "1v2". There are two guys there and I shoot one in the back. The second one is there but I wasn't that confident in the engagement so I left and let my teammates clean up.
At 1 min I am chasing a guy but he disappears into his spawn area. I'm guessing this is a situation you would push through? For me I didn't know which direction he went and looking at the mini map everyone on my team was still on my side so I just "camped" instead of running out in the open. What I'm doing here is rotating the mini map around and using my teammates as bait to figure out where the enemies are lol
Same deal at 3:10. I pop out and see an enemy but it's deep within his spawn. Not worth it.
The rest of the match is pretty explanatory. I never push too far up and when I do it's real careful and not gung-ho. It's not the most exciting stuff in the world but it gets the job done. Also, I'm aware that I'm a compulsive reloader and that I never should've tried to annihilate the guy on the rooftop but it is what it is
