Doing enough rolls to open up ones own bakery is a great expression <3
The thing about doing anything against shield pressure is knowing when it's usually safe to leave your shield and then mixing up what you're doing. E.g. against CF can't legitimately connect with anything after his jabs, so if you think he's going to stop his jab sequence that's your cue to do stuff.
And yeah, most rolls can be substituted by well-timed wavedashes. The wavedash will leave you safer afterwards, but you can roll out of some things where you can't start up a wavedash before getting hit (and rolls are super easy to time, since you can buffern them with the c stick).
Always remember: You're not a noob for rolling, you're just a noob if you get punished for it.
