Best agent for beginners

I am a beginner in this game and after trying to do my best with every agent available from the beginning, I felt very comfortable with Jett. Her power ups are very simple and efficient no matter what position you want to take.

I think Brimstone is a good one to get started with, fairly simple to use, you can help out pushes and holds with smokes and beacon. The molly is something you'll have to get a little familiar with + lineups
