I am new to the game and to shooter games but I am liking it so far. What do ya'll recommend I do to get better at the game?

What should I do if I die in the bonus round but the team wins? Should I buy a rifle? Specter or just a sheriff so I can full buy next round?

I've played almost every agent competitively now. I can safely say Breach, Astra and Viper are my least favourite agents to play. Breach - His concussion and that explody ability are super easy to avoid. Amazing flash though. Viper - Mana...
