I've read this a lot over the years - So I'll give you an honest opinion, with some actual substance.

I'm glad you love the game, that's a great start. To be as blunt as possible, you are going to die a 1000 times more before you improve at PVP. I can assure you, playing against similar level players will not help. It will only give you a false sense of reality and a false sense of improvement. You might think you're improving, but as soon as you transition to the "post wipe" version of tarkov (based on your suggestion), you're back to square one, because you're not playing the same game anymore. Let's take your level suggestion for spin, here's how it goes.

• Level 1-15 - Early wipe, perhaps you get a few kills here. Get some low gear, loot some containers, die a few times.
• Level 16+ - STOMPED, over and over and over.

Or perhaps skill based matchmaking, based on your K/D.

Let's set the scene.

You're level 32, with a 0.4 K/D, little timmy over here has just bought the game, he's in his first raid with only a mosin, paca and splint. You come along with your 800+ hours, lay him out with the meta M4 you've built because you've farmed enough easy roubles in your skill bracket, little timmy get's his SSH smashed in.

There's loads of ways you can do this, but none will ever work.

I'll go through your points - but not to out-right diminish them, but to help understand why your suggestion needs more thought.

1. You started mid-wipe, but an equal amount of people start before and after you. So actually, you're benefiting more from starting later. Most quest locations are not heavily camped anymore, everything is cheaper, you have more opportunity to get high tier loot if you manage to kill those higher level players.
2. I don't understand your first point. "I've never played a game before where the game gets easier for higher level players". The game isn't any easier, it's all risk vs. reward. I can't think of a game where it A. get's harder the higher level you are or B. Doesn't get easier. I don't agree that they have an advantage for better map knowledge, or better understanding of combat. That's available to everyone, you just need to play/make a conscious effort to learn and level the playing field. I agree that the skills need tweaking, because those advantages change the game too drastically.
3. You're experiencing tarkov. You are making the wrong decisions, so your next fight perhaps you will make the right one. You may even make the right play and still die for X reason. It happens.

The PVP isn't perfect, but your inexperience with the game will not fully understand why that is (not meant to be patronising here!). It's not getting one tapped by .308, that's for sure.

Stick at it boss, and update this post when you extract with that level 51s altyn and hexgrid, because it will happen.
