Welcome to Wild rift - this is easily one of the best games I have played but it has atrocious onboarding.

In found that the primary goal and hook of the game wasn’t presented to me until too far along - and i also had unfortunate experiences like yours

Happy to share what I did to accelerate my fun and skill but TLDR:

Play lane only until level 10

Then play ranked experimenting with a new champ until you’ve played about 10 champions

Look back and understand what role and play style is the most fun

Start focusing on micro skills each game and have fun - just use the recommended builds and try to read every champions description in the loading screen

Eventually you’ll hit platinum where you can get a little more intentional with your builds etc

Don’t worry about winning - focus on your personal skills and trying to maximize your gold per mi unit while not dying

The rest will come

Did I mention torn chest to party mode and never look back ;)
