Suggestion: Keep the Intro Mode available beyond Level 10

Can we please keep playing Breakthrough and other modes in the "intro mode" even after reaching level 10?
I’m not a pro and already a bit older. In regular multiplayer matches I just get shot from every direction and have no idea what’s going on — that’s not really fun.
The intro mode, where most players are bots and only a few are real people, is perfect for players like me who want to enjoy the game without getting crushed all the time.
I’d really love to see this mode stay available forever, beyond level 10, and maybe even expanded to all maps and modes for more casual players.
