Targeting

I know there is the hover targeting for fighting and I have even heard that there is auto target but I have yet to see any auto target in game. I have issues as of late with super fast minions overtaking me because I cant target easily with ranger class. It seems unless you use multi-shot on everything you are pretty much left to your personal reflexes to deal with single targeting. Am I missing this or is it not there and may possibly be added later?
