I have searched around and found a number of posts on melee IWT problems, I'm currently using the spam method to keep the melee swarming around the enemy in pvp.. Although I still get problems between targets.. I have had an idea but don't know if it would be possible to do? I'm not entirely confident with wow macro or if it is possible through Isboxer

At the end of my spam keymap in isboxer I would like to add a macro that checks if the current target is dead or if no target present and follow the current Jamba master if true:

If target isn't enemy (dead, friendly or no target)
then follow Jamba master
else do nothing (continue with attacking target and IWT)

Thanks
