It is very easy to eliminate. All you need is additional target cursor for each action (like the one we got for cure, provoke, etc.) and <st> <stpc> <stnpc> tags for macros. 1st offensive action on target should move main target cursor from your mage to that target (unless youre locked). Its like million times better than current retarded targeting modes.

Now its:
1. Switching to desired targeting mode
2. Choosing target (and mistakenly lock on your mage from time to time)
3. Choosing action

Should be:
1. Choosing action (and automatically switching to targeting mode proper for that action)
2. Chosing target

Same effect but fewer steps and no accidentally mages targeting or targeting mode switching. Plus you can target team members with up/down directional buttons. Of course if youre already locked on desired target and just spamming one action you will need to click twice instead of once. That is why we need auto-attack
