I have my tab button bound to "Cycle through Enemies (Nearest to Farthest)" - and I think they messed up the wording cause it should read "Cycle through Enemies (Randomly all over the map)." I have found tab targeting to be utterly frustrating when there are multitudes of mobs around you.

I tab to attack the guy at the end of my spear...and start attacking....to discover 3 minutes later that I'm standing there looking stupid cause my target is 30 meters away across a field. So then I tab again to get on target, to discover that now my target is still 30 meters away but on the other side of the field. And to make things worse, this new target is from an unaggro'd group that is no threat to us and sitting around enjoying its coffee.

How do you guys deal with this? Has this been the way it's always been in this game? Why would tab cycle through mobs not even involved in the current encounter, when I'm standing in the midst of half dozen that are? I'm surprised that this chunk of code exists in game. I've played almost all the tab target MMOs and never seen anything like this.
