Druid Charming Question

[Malik_Gynax]

So let's say I'm charming two mobs as a 33 druid.

My pet is losing the fight slightly. This is a good, because I can throw a DOT on the target enemy or put a damage shield on my pet. This will even the fight out and I can expect to break charm and kill them both with melee or a nuke as they both flee the fight at 5-10% HP. This is my ideal scenario.

Now let's talk about the opposite scenario. My pet is WINNING the fight. The target mob has a slight edge, which is likely going to result in the target mob hitting 20% and starting to flee. My pet will still have 40% HP. So, I have to break charm on my pet and root him. DOT the ex-pet, melee the original target to death. Come back and probably nuke the ex-pet then melee him down.

This second scenario takes way more time and mana and I would like to avoid it. Is there anything I can do to give the non-charmed mob the edge in a fight with my pet so that I can keep them even?
