I agree completely!
The best thing you can do is ignore them, the "professionals", and enjoy the game, compete with your friends, click the paragon points one by one if you prefer.
They always use bot, turbohud, 3rd party script, whatever to call everyones attention. Don't you think for a second after a possible ban will stop them cheating...
There is one thing to consider, learn to do it yourself. I'm exclusively a PS4 player (been playing Diablo since 200ish). I kept seeing builds recommend the auto lock feature on certain skills, Devour in this case. So I cracked open a PS4 controller and made a switch for auto-push a button (R2) just for Devour. It made those builds requiring that function access able now. This doesn't apply to cheats or crappy stuff, but learning a secret to the system you run without obviously giving you a huge advantage, then go for it. Just don't do stuff that makes you 10,000 times better than the normal player (which I rank a few levels above casual).
All in all, if you have fun then just play. If you want to learn all the tricks, then learn them.Just don't do something that gets you banned or have an unfair advantage over your mates.
