see specifically i really didnt like the ar2 because it allowed you to actually exchange shots instead instantly kill targets who rely on single blowslike theres a sort of rock paper scissors to ranged combat and it all revolves around skill; if the enemy is using some weapon that relies on many shots to do damage, you shoot them once with a powerful one-shot weapon to kill them before they can fire enough shots to hurt you. if the enemy is using a weapon that fires one shot but with a cycle time that leaves them vulnerable, use an automatic weapon to hit them while they're reloading and defend yourself or make yourself hard-to-be-hit while the enemy is firing their shot, dampening the damagein essence just use the type of weapon they aren't usinglike you can hassle zombies no problem with smgs pistols and the rifle because they're slow and they rely on hitting you once while you're not paying attention. so what you do is dodge them, then while you know where they are (and have not leaped) lay into them with an assault rifle instead of wasting shotgun ammo on them and possibly missing

wait but like no combine was ever a threat at all everyou just go HA HA I WILL SHOTGUN THIS MAN IN THE FACE and you shotgun them in the face and the threat is instantly solvedlike even en masse you just shotgun them and then skedaddle the forget outta there when you need to reload (if you need to reload at all) and then waddle back into the fray
As someone who has played Half-Life 2 on the hardest setting very recently, i can say that even with a shotgun, multiple combine and especially the ones with red eyes will take you to a stuff tasting contest before you have enough time to reject their offer.
Pro snipers in TF2.If you get stuck against someone who is really good at sniper against you, you are pretty much screwed no matter what.
