The Haida is super fun, even with a bad win rating so far, the ship performs very good. Like some of the community contributors have said you need to be very comfortable in close combat with destroyers and you need to be aggressive. Newer destroyer captains will most likely struggle with Haida, but if you figure it out she is a blast and very deadly.
Learning when to use single fire or group fire is key also using them in groups of two is very effective. Fire the first two hold then send the second two gives you a better chance to land hits IMO, it has worked for me.
When creeping along in her smoke be careful as it makes it a bit easier for enemy ships to target you in the smoke. Just keep that in mind with smoke firing at medium to close range. And speaking of her smoke its easy to glide out of it in reverse, most of the time you should keep moving forward. Play with the throttle from 1/4 to stop so your not always at the front edge of each puff.
