Looking For A Grinding Spot For Level 84!

As the title says, I'm looking for a good grinding spot for my level 84 assassin. I have already tried the Thanos vaults, which apparently got nerfed with the spawn rates, ToA and Hive, but none of these seem to work well. I've looked on youtube for guides as well, but can't find anything. Please help!

 

You should try the freezing hights which is effective on levels 80-100.

 

I have tried that as well, but because they're level 90, they're hard for me to kill and don't give much exp.

 

Right around here is a cave filled with melee fire mobs. You should be able to get decent XP and you won't have to worry about dying if you stay aware of your surroundings.

 

I'm using that place all the time, and I'm level 83. Trust me, it's effective. It's just the fact that on high levels you cannot level up fast.

 

Another relatively good spot is in the Hive, Earth floor 8. They give a lot of XP, but not very high spawn rates
