Ay for sure!
Their names.
Fright T1 -> Dread T2 -> Fear T3 -> Horror T4 -> Terror T5.
Yes sadly you would have to kill the first 3 tiers each game before being able to get sunders from tier 4 and 5. But again after the first tier 5 it will always be tier 5 for that game.
For people with reallife this will be ultra rare to farm online (p1). I cleared whole act 2 and act 4 and only 3 heralds spawned. It took me 80 minutes.
Then the game crashed.
Im not complaning that the drop is rare, i am conplaining that you need long sessions. I often have time for 20-30 min sessions, where you can farm good oldschool style - but that new system need extreme long games-sessions, which i havent time for.
They should increase the spawnrate a lil bit for those fellas.
Maybe its their anttempt to counter boters? Who knows
