hem i watched video and i can still confirm that in not watching wak video and doing the event live on official server on pc as i did with 2 thralls and they did not get xp when you kill the commander and finished at level 4. but for console this not patched yet.

have you personnally tested the event to check it on pc ?

and believe me i will be the first happy if was still working as i got 20 thralls level 20 killed when someone raided me 4 days ago (and all thralls killed in 10mn, deadly tthralls…really…)
