Hey.

For IWT your guys actually have to be in melee range for them to 'interract' UNLESS you enable Click To Move, which then makes them run to their target.

For the round robin, if you have isboxer v38 then the idea is to add an ATG (action target group) and put your shamans that can thunderstorm in this group. in your keybinding you enable round-robin and the target needs to be the newly created ATG. This will then make the mapped key cycle the macro through each toon.

let me know how you get on
