Is there anyway to tab target like in WoW?

[DonS]

Is there a macro or something to make it like targeting in WoW?
By tab targeting like WOW I mean:
1)If no target, target nearest enemy
2)If target, target nearest enemy that isn't already being targeted
3) Target stuff I'm actually facing
4)Only target stuff i'm in range of

I know you can keybind TARGET NEAREST ENEMY or CYCLE THROUGH TARGETS (NEAREST->FARTHEST).

These suck for me however. When I target nearest enemy it will only target nearest enemy. When I hit it again it stays on that target. When I try to use the cycle through targets function, it will cycle through a million different targets from around the world that Im not even facing or in range of before it finally comes back to the original.



Also I am probably going to be a scholar. Can healers solo in this game?
