I've only played the Okhotnik in co-op so my opinion may not match those who play it in Random games but I love it - Cruiser levels of gun damage (and reload sadly), 12 very hard hitting torps for the tier which reload in 40 secs with commander skills which are great for ambushes (2-3 torps can sink most cruisers, 4-6 most BB's) and I love that you can launch 2x3 to bait people into thinking you're all out, surprise them with another 2x3 seconds later. Relatively fast at 39.5kts with speed boost flag but turns like a cruiser rather than a DD and had OK concealment for the Tier at 5.9km with captain skill.
TL:DR Cruiser firepower and handling with DD concealment and health.
