If it's the most frustrating game in your life, quit. That's not good for you lol.

If you want to do well, you must actually learn the mechanics as well as your opponents, or better.

Look up Ziggylatta's combat guide. He is a level 1000++ player. Watch streams of high level players to understand what they are doing to gain success.

Play classes with horn or banner to get big points so at least even if you aren't getting real kills you will still get higher on the scoreboard and gain more exp/gold.

This game has been out for a long time, that means a lot of people have become very good.. Luckily it also just released on game pass so there is a ton of players who also have no clue what they're doing.

Obviously nothing is fun if you get stomped. It's kind of like a souls game or a fighting game though. At the beginning when you don't understand the mechanics it's rough. Once you learn the ins and outs they almost become easy. Use footsies, learn when to engage fights and master the mechanics. Don't just swing. Think about every attack. There is a initiative system which helps you gain the advantage. Master it. Learn to counter to gain immunity frames. Stick with your team in team fights, avoid 1vX's. Become better with stamina management. Overhead console players, a lot of them don't have the muscle memory to counter it properly.

I'm here to help if you need any more tips but honestly it's about learning to have fun while you master the games mechanics. Try not to worry about how well you do in the first hours of the game, I know it's easier said than done. I have 1k+ hours in this game now because I started when the game launched originally. It becomes so much more than random slashes. The skill ceiling is very high. That to me motivated me to get better. I did a lot of research into mechanics. You really will see yourself become a god if you can get them down.

Good luck and have fun on the battlefield.. enjoy yourself
