I guess each person has to weigh what is important to them when it comes to root or not. I used to root every device I got that could be rooted. I'd flash multiple kernels and ROMs and forever tinker. I used Titanium backup as well and often found it invaluable due to the screw ups a new flash would bring.It always boggles my mind when people say root isn't needed.
Perhaps that's due to what features an individual uses.
For me, I'd love to have root for titanium backup and for being able to have all apps in multi window.
I am aware of the helium app for backups but helium can't backup all apps, and nothing other than root can put all apps in multi window.

That being said it would be nice to use any app in multi-window but that's not enough to get me to root.
With the Note 5 I told myself I'd run stock for a while and see how it goes. That was mid September and I have not missed all that root fun yet, and I'm loving Samsung Pay.
