i think it is important to always try hard and challenge yourself. there is nothing wrong with saying that it is easier to control a group of monsters if you are the one who makes the pulls
Why don't you try binding killtarget1 to a key and setting it on the current monster that you want dead? set the mark while you are running to the target and change it to the next one as the marked one is about to diePeople are always in a rush. I take a second to mark mobs, but that second is too long, so dps aggros everything and the marks become pointless.
worked fine for me while i was leveling up
