A way pointer that shows where each thing is. For players who seek to finish there quests. I find this very annoying. I am in a quest and no location on it. It makes you want to quit the game. An auto pointing or marker could help with that. Auto attack so you can keep attacking the enemy without clicking all the time.
Auto loot and all items I am not wearing selling to vendors. This could be very helpful to players like me who picks up everything. Right clicking all the time is time wasted. Also auto loot pick up.
Key note. You would be able to turn this features on and off. For players who don't want it on.
