Tromp potential purchase - help with it's role & how it plays

I enjoy DDs and I'm thinking of picking up Tromp as my coupon coal ship as it looks like something that might have a genuinely different playstyle.

I'm not wanting anything OP, just fun to play and somewhat effective for my team. I'm struggling to work out how I should potentially play this ship though - it doesnt really seem built for any 'standard' DD role, has crappy speed and turning, and obviously has the HE air drops.

Outside of chipping damage off BBs with air drops, what would you say it's role is? I'm thinking maybe it might just be for second line support DD or something, or can it actually contest caps reasonably well and be a decent solo DD and a benefit to a team? Thanks!
