I think you're really missing the point. Aside from relegating 240 points to 'supporting other people to get rights', in practice even the buffs from the Prov Mastery are only mildly useful at best for the healing factor, given that most dexxers already cap their HCI, DI and stats. Tieing up the spawn doesn't get you drops. Armory yields no rewards. You can easily Dispel and resummon.Actually I use provo pretty extensively. In guild hunts I run both provo masteries in support of the 'team'. In shadowguard roof I provo the things the bosses summon onto each other, getting them off my team mates. In the armory I use provo, disco and evs to solo the room. I also often use provo to direct my EVs where I want them to go instead of letting them roam at will.
(N/A meaning not applicable/nothing to Provoke, can't Provoke, or won't get you rights anyway.)

I'm sure I missed some but out of everything in the game that's worth killing for a reward Provoke currently can get you Replica's from Ilsh spawns and drops from Doom. Both of which are largely outdated in terms of usefulness/value.
I'm not saying it's not useful for some stuff, but compared to what pretty much any other class can do with 240 points it's a joke how consistently it goes overlooked.
