This is easily overkill, and likely will work for Nightmare, but
things to bring to hydra
provoke
block buff
Inquisitor shamael or a veil champion
hex
after you meet those requirements aoe damage and support.
It is a pita but learn what the heads are doing and depending on your team know what head is the most dangerous and target it.
There is no reason OP isnt doing at least brutal with that roster. So the problem is probably understanding the fight. I dont blame OP for not learning it as hydra is the worst addition to raid by a huge margin. It is so bad it makes wallet vs wallet seem good.
