The purpose of this video is to demonstrate my latest iteration of the Ranger ultimate build that I use for competitive runs and not to maximize the ultimate damage.

Yes,
1. It's possible to achieve more ultimate damage,
2. I do have components with +75% ultimate damage inscription that I can use to replace Elemental Ops, and
3. I can use Rampager to increase my ultimate damage.

But, there's no need to do that, given that:
1. All those I want to target with my ultimate die with this setup,
2. This setup suits my play style, and
3. Most importantly, I'm able to support my squad without holding them back.
