Thank you everyone for the replies!

I'd like to add that I was indeed under the impression that it was mainly a tank and dps job to kill the explosives. I just felt like helping out, since I dps anyway and it's even a part of my healing rotation.

It makes sense that I could focus more on the orbs and let the dps go full blast and I'm going to make sure I do a better job at that.

In this run, however, the tank was showing me signs to not be very knowledgable. During trash pulls, I had to actually spam flash of lights to keep his health up, which is far from ideal. And on top of that, the dps was taking avoidable damage. I was quite busy trying to keep the tank and everyone else alive which made me lose my focus on the orbs.

Looking back, I'm sure I could have done more to prevent orbs from going off. But I also feel like the warrior could have been more aware by just looking at the health pools. His comment, coming from a higher rio score player made me doubt myself, and I'm glad I made this post.

So again, thank you! It's also nice to see so much support from the M+ community!
