I did not think to check this, my dps rotation does not have anything with a cast time. Gut feeling tells me it will be interrupted and melee will need to stop DPS to cast something.
I kindof see that as a problem easier to fix. For example if you have an Action Target Group for melee and you send IWT->melee you can have your flash heal keybind first remove them from the ATG before casting then return them after.
Thanks for the feedback. That's definitely more food for thought and something I have to look into.
