RG is better than Trunda for Hydra 

Lydia (with Shameal if torment, otherwise tougher to use).  But if no torment, automatic.  I have Shameal so, Lydia on A team.  

But on hard, can probably jus power nuke with Lydia and 2 rg.  I did all Brutal last week so we could kill.

No Shamael, remember :)

But yeah if there is no Torment head I can see that working. I tried a similar version, but Torment just messes everything up :/

on Brutal/NM I definitely agree

I think with the HP nerfs it gets a little murkier if you're able to speed run Trunda nukes against decapitated heads

Lydia, Arbiter, RGs, Ninja, Visix (mainly for Decay protection), Ursala are all fairly strong options overall. I think generally speaking trying to nuke vs. Hard is better than the max HP and even Geo strats, and a few of these would help there.

Deliana is also very underrated on this rotation due to affinity. 

The problem with any of those nuke strategies is Torment. He just completely shuts down aoe nukes unless there's a way to deal with the fear. Doompriest handles that nicely, but not with Lydia - essentially Lydia becomes useless. And Lydia is the only champ I have with an AOE DEF down + Weaken move.

There's just so many pieces necessary to counter the other heads that I can't find a way to make those nuke strategies work. Mischief typically needs at least one person to handle, and if Decay ever spawns that's another big problem :/

Fair enough. Sometimes I might forget how much Shamael trivializes things. :)

I'd want to slot Lydia in the Rector team, for sure.
