For ranger dps:
1. Max AAs
2. Get best bow you can
3. Get best arrow you can
4. Get best quiver you can
5. Get type 3 augs
6. Load up on hdex everything
7. Use Ice Burrower Swarm (or whatever big dot you have
8. Rotate through (I assume lvl 115, if lower, adjust to the lower spells) Marked Shots, Focused Blizzard of Arrows, dicho, and Summer’s Sleet. Weave in jolting kicks, blizzard of blades, and kick as you can.
And use your AAs and Discs liberally. Outrider accuracy, spire, guardian, group guardian, etc should ALWAYS be on cool down.
If you do that, you’ll see great dps out of your ranger. If you don’t, it’ll suck because how you setup the ranger sucks.
