Dear Blizz,
I was just doing Avanoxx on an Ara +10 on my alt, and it would insta leap across the map to eat the starving spiders. This enraged it and we wiped. I tanked it across the map and it jumped after 5s on the ads. Maybe a bug? If anyone else encountered this let me know. Again, I tanked the boss all the way across the map from the ads and it still jumped.
Best wishes,
Muradun
