[Q] Should I root if: topic

The only thing I want to do and can't make work is the Wifi Hotspot (I used FoxFi on my old phone and I loved it and have already paid for the license, if using it is possible)

My concerns in order of importance to me:

1. Stability is critical.


2. I don't want to own a 0 brick.


3. I need to be able to use my unlimited data plan to create a hotspot several times a week.


4. Not voiding warranty.

If the advice is to root to achieve this function, what is the safest rooting process, with the most reliable outcome for my above 4 concerns?
