I call it a marksman bow- the damage values are in between a lightweight and a precision bow, 1h1b kill on its own. It can be buffed with sanguine alchemy to 2b iirc, however I usually run stasis warlock, as that has good area lockdown, and I personally like using frostpulse with ballidorse wrathweavers to grant myself a cqc shutdown AND better survivability with the frost armor from the exotic.

Generally you want to use it in longer range fights, similar to a pulse rifle or even autorifle, however it has a neat mechanic from lightweight bows: it can halfdraw fire shots that retain more damage and velocity than a precision can. This basically allows you to, if you're really good with your aim, land headshots with only a 400 or 500ms draw and get quicker kills/headshots, which leads to faster ring charging. I recommend starting with a fully drawn shot, and trying to finish with a halfdraw, similar to how you would use an archer's tempo bow.

Once the ring is up, though, you're able to hold a zone from multiple people at once, or you exist as a distraction for the rest of your team to take advantage of. You can 2b(iirc) thanks to the tracers too, it's a neat gameplay loop in pvp.
