Bug description:
Using Typhoon talent as a restoration druid on enemy NPC will reset our ally NPC threat order, making them attack the closest enemies instead of continuing from before.
This is major, since normally the first enemy targeted should be Corrupted Risen Mage (https://www.wow-freakz.com/npc_finder.php?npc=119478) who have a stacking damage buff that will oneshot our team if left alone under 10 seconds.
Since Restoration Druid dont have innate CC or interrupt, we have to use either Typhoon talent (30 sec cd) or Mighty Bash (50 sec cd).
Mighty bash cd is too long, that by the time next wave come, it's still on cd, and currently if you typhoon the mage to interrupt spell, our team will change dps target into other enemies, ensuring a wipe (because the mage will oneshot them soon after if not killed first and resto druid dont have any more interrupt/cc to spend other than that one talent taken).

Proof:
1. screenshot of our team hitting soldier instead of mage after a typhoon (https://imgur.com/a/GdIDX93)
2. video from retail 7.2 at around 2:16 mark where after typhoon, our team still target mage first ( https://youtube.com/watch?v=Ynh90dN0Qe4&t=136:

)

from what comment I gather, our team should attack mage first, then soldier, then archer, always, unless the preferred enemy are targeted by hard CC that canceled on damage, such as Monk's Paralysis or Paladin's Repentence.

Confirmed, having the same issue.
Since druid has no other option onresto mage twer challenge, it is almost impossible to complete.

Same thing with paladin heal using Repetance.
