I think after the most recent threat buffs a little while ago tank threat has been generally pretty solid. As a dps who isnt playing rime I feel like I never have a problem with it.
However, Rime continues to be a menace when it comes to aggro. Even without the weapon there are situations where she will just rip off the tank deep into the pull with a strong enough freezing torrent.
Tanking with a Rime and without her are very different experiences. The cognitive load of playing aggro whack-a-mole is so much lighter without her.
I do not believe the fix to this is to bump up tank threat again.
- The weapon itself should just not give threat at all. That alone would be gigantic,
- Her freezing torrent should also do less threat.
These 2 things would go a long way when it comes to making tanking at a high level more fun with a rime.
