In addition to the normal ZigZag method (link to old post here), I found out myself how to do a more effective ZigZag !
Super ZigZag
While tapping strafe-right and -left buttons, press and hold both mouse buttons down and move your mouse to the left and right rapidly and repeatedly.
Works great against melee mobs! I figured, this way you will escape quicker.
Another way to achieve this is to tap strafe-right and -left buttons really.. really.. quick. But my method is easier to do, I would assume.
I apologize for making a new post about this little addition but I am not allowed to bump the only thread I found about zigzag because it's more than 255 days old.
I hope its useful and Have fun with it ^^
EDIT: Of course I did a search before posting, and the only relevant post I found is the one I mentioned above. I am unable to post as comment there because the thread is > 255 days old
