Kinetics plus Typhoons seems like a really good build for it to me. This specifically is with Ordnance Expertise *and* Flux Regulation, but even flying it myself without OE, it felt pretty nice - and with Missile Spec on the officer, it really doesn't need the builtin EMR that much. Could probably build in ITU plus something else instead. 3050 kinetic damage per full burst quickly gets destroyer shields into a range where a reaper can overload them, and a reaper-induced overload (especially if it is from two reapers hitting) gives enough time for you to get another volley in.
And yes, while I am playing with Starship Legends, this specific ship doesn't have any traits that would affect its flux stats - Ordnance Expertise is just that good.
