I understand why heroes always tend to target your target, and for most builds this is probably something you want, to quickly spike mobs down. However, sometimes you want a certain mob to stay alive.
For example, if you're running Spiteful Spirit, you want that mob to stay alive the longest so he can pump out damage to all his friends. It's pretty frustrating when you hex a mob only to have heroes all spike it down before your hex can do any good - it makes you fairly useless to the group, favoring only builds that just put out quick damage.
If you could have an option such as "target my target" or "target my target last" it would give a better range of builds for people who play with heroes mostly (most people) to use I think. More control is always a good thing in my opinion.
