If you've got it set up right you should never have to take control of another window in combat, right up until the character on the main one is dead.

You need to have your normal movement keys bound so that with a modifier they can control the slave (I use shift+WASD for it's lateral movement, and ctrl+AD to turn it).

You also need to have the healer set up so as many of it's abilities as possible are passed through HKN. You can use HKN's <If MouseIsOverWindowRect> conditional to pass click casting over to the healers window, which will free up a lot of keys for other abilities the healer has.


2 boxing high levels I've only had my 78 warlock's pet available to tank with, and even doing level 70 stuff (and trash pulls in MC) I was only really successful because I was healing with my 80 disc priest, which can also put out DPS while not healing. A tree form druid has the disadvantage that it can only heal unless it shifts, and it can only DPS at range unshifted, so becomes more susceptible to damage, not to mention the delays and mana use that shifting cause.

Tank and healer is hard to do, because you don't really have the DPS to kill things before they wear down the healer's mana, and boxing you tend to take a lot more damage from AoE than a normal group, simply becasue of the independent mobility issues. Becasue of that there's less mana to go round. That's not a problem on trash where you can always take a break between pulls, but on bosses it becomes an issue, and yeah some WotLK bosses do have overly complex fights, even for non boxers.
