Hi,
Unless you need root for something specific, there are tons of no-root apps these days, and if you need certain extra performance from an app, there are ways to provision them by using ADB. It basically allows you to add special permissions to an app to get added features because of Security restrictions on newer OS versions. The guys over at XDA Developer's are always coming up with some great hacks for exiting apps.
Aside from that, global adblockers are out there for no-root but, you have CTO find them in other app stores, like XDA website, F-Droid, or even Apk Mirror. These are safe sites and stores for apps other than playstore, and open source in many cases.
