I'll tell you one thing, starting the game as a new player in which it's mature (been a while since a reset) is only suitable if you are a masochist.
Let's go over the hole you have to dig out of:
1. 9 out 10 PMC's you will go up against are Fort/Kitted M4 super soldiers who make you vaporize. (And these players mostly started at reset, meaning they didn't have to go up against fully kitted PMC's as they progressed, hence had a much easier time of it).
2. You have no trader rep so you cannot buy any armor or any guns that aren't shooting spitballs.
3. Many raids of gear and time are lost due to bugs/DeSync/Dying to silent AI.
4. Playing as a SCAV with a pistol or TOZ-106 is a complete joke versus PMC's and only good enough to kill AI SCAVs just so you can get a shotgun that isn't completely worthless. A shotgun that is worthless outside of Factory.
5. Leaving the most effective way to level yourself and traders being hatchling runs in factory (which I refuse to do because it's stupid as hell) but is completely ruined by 30+ minute wait times to get into said Factory.
This is a REALLY bad time to start as a new player. May wait for the next reset in which I am not up against prior reset advantaged super soldiers and hopefully many of the game breaking ridiculous bugs and desync will have been looked into.
Before the last wipe I started in those excat circumstances and yes it was brutal but certainly not impossible, it's so refreshing not to have a game handhold you through the entire time.
1. Going up against geared pmc's is an 'option' most of the time, if you're careful with your movement you can avoid them easily. And also the vepr 136 is a great early game weapon, use it with PS ammo and it will take down any PMC. Ammo is very important make sure you're using armour piercing rounds.
2. Working through prapors missions for rep is pretty easy and gives you some objectives during the raids. Skiers first mission is poorly designed though :/
3. That's subjective, I've not lost anything due to connection issues (EU)
4. Scavs runs you will die 90% that's the idea, but its risk free. Don't see the issue here, it just a way to get a bit of free cash.
5. Learn and play customs, factory is a terrible map for low level players. Most of the missions are on customs as well.
This has worked for me so far
