Nice job! Grimrail Heroic or Everbloom Heroic might be good ones to try next with all locks. Shadow Fury and Howl of Terror will come in handy. Having 5 of them is going to work out very well against bosses like the Protectors in Everbloom Heroic and Yalnu in Everbloom Heroic. You can keep everything perpetually stunned.

Good luck with the team, I bet they're a lot of fun.
