That right there should definitely not happen and is something that should be addressed in the future. Channeled sc's shouldn't be able to get interrupted. I agree that Gadget is by far the most fun power to play when it comes to might due to its ability to not rely on channeled abilities entirely. However, like i've shown, its still possible to play it that way, just not with the most effective artifact "abuse". ("Abuse" since the artifact is balanced to be cancelled at 10 stacks and everything beyond that is on your ability to manage your health/powerbar or the healer keeping up with your shenanigans.) Just because you can't play a power to its former full potential doesn't mean its broken.
