i have a few questions regarding the wotlk hunt. i played hunt since 2011 and i haven't see anything about this matter in bug tracker, so i'll ask around here.
i'll make this simple with this rotation:
- pet die when mount - unmounted (happened after server wiped on February)
1. pet die
2. then hunt die
3. when i re-spawn, my pet come back alive
4. then i mount
5. when i unmounted, my pet die again
- pet's health reduced when mount - unmounted (this is also happened before the server wiped until present day)
1. my pet is in full health, say... 20k hp
2. my pet die
3. i ress the pet, pet come back alive with 3k hp
4. mend my pet until it reaches full health
5. then i mount
6. when i unmounted, my pet's health went back to 3k hp
The pet losing like 20% health after mount/dismounting is a known molten bug which has been here since 2009, idk what the first thing is you mentioned is but I can imagine it happening. I don't see molten (oh wait it's warmane now) fixing it since it's been there for so long and it doesn't impact us in a game-changing way. It's a bit annoying, that's all.
