Let me preface this by saying that Hyde is by far my favorite Hunter to play as, and I will continue to use him in PUGs.
Right now I don’t think there’s any real reason to use Hyde except as a method of unlocking Parnell. I say this because his flamethrower doesn’t seem to have much of a DPS advantage over Markov’s lightning gun. This should be offset by the lightning gun’s much longer reload time, but Markov’s mines and secondaries far outweight the small benefit to DPS that gives.
Hyde’s gas grenades appear to do as much damage as a single mine if the monster remains in the grenade for its entire duration.
Taking into account how useful mines are for players other than the Assault and how Parnell’s damage easily beats Hyde’s even without super soldier, I can’t really think of a situation where Hyde would be a reasonable competitive choice. If I feel confident enough in my team’s dodging to not go Markov then I’m going to go Parnell for his clearly superior damage.
If I’m wrong please correct me, I would like nothing more than for someone to show me melting the monster’s face is viable in comp play
