vVateshran build

Trying to do vVH run to get the hero the undying song achievement, in particular Vateshran's chosen achievement. I have access to all classes, all normal trial gear, all scripts for any possible combination, and any craftable gear with a cp 1500s.

What would be the best build to do vVHs run in under 45 minutes. Any advice, is appreciated. Mechs I've got mostly down, but the DPS I feel is slow going for the timer.

I can gold out gear as well, just need to know what would be the best class, skills, and gear to get through it one shot. Thanks to all who commented and helped! 😁
