The new purge t4 Thrall pool is the same for both EL and Siptah.
The pool includes all Siptah Surge fighters, archers, dancers and bearers. It also includes all EL fighters, archers, dancers and bearers.
On Siptah we have rescued RHTS, Cannible Brutes, all the EL t4 Bearers, t4 Volcano Archers and lots of various dancers.
It’s completely random I can tell you that. I only play on Siptah, so for me getting the EL Thralls has been fun.
The EL Bearers have a way higher HP pool then the Siptah surge Bearers. Highest siptah bearer I have seen is 8k. Highest EL bearer is 18k. From that perspective I have been loving the Bearers.
Prior to the new purge system Siptah couldn’t get Cannible Brutes, Devotee and Thugra. It’s been great to hear that Brutes are possible now. Still can’t confirm Devotee or Thugra.
