Sunsinger has melee and nade, and it's been widely accepted that they have the strongest melee nade setup in the game. Considering that those affect near every encounter you'll have, I'd say you should have no complaints. In addition, blink strike isn't a ranged melee, nor is it the topic here. (FYI I've literally never run backstab, always fast twitch hungering blade). I agree the backstab hits can be bs, but they're not related to the topic, or even the same subclass. Mobility is what makes NS strong, the nades are weak and don't have tracking like bolts, or burns. The melee doesn't buff the user like a sunsinger, helping it win near every CQC. Only when used together are they ever likely to get a kill, or, see use at all tbh.
