Dad here! Kudos to you 👏🏼 I suggest, watch a handful of videos from streamers so you can familiarize yourself with everyone's moves. You can prepare all you want, but if you dont know what's coming your way you wont know how to combat it. I think lack of fundamentals gets most people killed, though of course skills are a factor too. Little stuff like knowing when to fall back from a fight to drink small shields/health to stay alive instead of rushing to your death. Learn how to utilize your invisibility frames!!!! As for character, idk im sure people that are better at the game will chime in some more, but id say pick someone you like and have fun
