that can work, but then every class would need to be reworked to fit in the no targetting system. Every ability would need an manual aim or aoe component to it. Wow is a 15 year old game, i dont think this is what the game needs.
What you don’t enjoy the game auto targeting things far away while in combat after your current dies, thus forcing you to tab back to the next mob?
Hope you hadn’t thrown a judgment or hammer of wrath.
On a positive note, it lets me know when I missed those jars. 
Click stuff when you cannot afford to have tab target fail. Calmly and methodically click it. You may have to turn on health bars because that can help.
I use the mouse to pan my camera so 85% of my game time the curser is missing from the screen. That’s a problem when your trying to click something in a hurry so I set up a weakaura to track my curser when it’s missing on the screen. That way you know where the bugger is, when you’re in a hurry. If you don’t pan with the mouse click this will not make any sense so disregard it.
They want more twitchy/shooter style combat where you don’t actually target as much as you face the target.
The problem with tab targeting is that the range has been increased. This becomes very apparent when I play classic.
