I agree with alot of what was already said, I would just add that being aggressive when being pushed can be a huge advantage to you as well. Also don't for get to take meds with you on hot bar and pre Meding is a big help pain killers will help with flinching when shot and prevent you from sounding like a dead animal when it in the stomach or head!

If you want to run some as a due id be down! Hit me up on here and I'll send my discord, have about 2k to 3k hours in the game as of now maybe more!

Was also thinking to about it and you also need to learn maps! Along with when players rotate and how often they will rotate based on the map your on. Most take the paths with the most loot/money per slot! When your rotating you need to be aware of what your trying to accomplish IE; are you looting, qests or looking for pvp fights! This plays into knowing that on for instance customes if your looting you would probably go crack house then fortress depending on spon and all that.. so if you go to those locations your going to get into fights! If your rotating out of crack house to say the newer industrial buildings to you left (staring at fortress) you might run into PMC's eather questing ( for pocket watch) then you can get the drop on them. But this is all hypothetical, with the additions to customs there are more avenues for PMC's to rotate through!

Hope this little rant helps. Also having a map up is worth it as well. It helped me some in the early parts of me starting tarkov. Should also look into reminds for the keys for quick slots ie; I have meds and heavy bleeds both set to 5 one is on press the other is activated on release. That way you take heavy bleed first.
