As an SLH you could fill up a slot in a nuker setup, as a third DD. An archer party that runs with 2 TRs could benefit from your Pride of Kamael as well.
And almost any party can benefit from your eventual Inspector subclass, in both pve and pvp scenarios.
As far as physical offensive skills go, I don't think they can provide the spike damage necessary to make you a real DD.
I am not sure if the land rate and reuse of Lighting Shock allow you to be an integral part of AoE parties, but they might.
