I wanted to add that driving from your melee is the way to go. You're overthinking the "keeping ranged at range" issue. Make sure that you bind your arrow keys to only move slave characters, but unless you are in dungeons (and usually even if you are in dungeons), there is no harm in the hunter staying on follow and sticking with your melee. Using IWT to send your melee toon off to attack things with your pet can be fun, but if it is annoying you (and it sounds like it is) just lead from melee. Even in dungeons, unless it is a boss fight, stuff that cleaves is much rarer than it used to be so sticking together in a group is probably the way to go.
