It's nice to see how someone's approach can differ from most "vocal" solutions.

Do you play around with slowing pets? Because I think 273 doesn't look very attractive, a safe threshold for PvE seems to be at least 277, as far as no epic/legendary pets are concerned.
I do like the trick for the menagerie.

I'd like to tell that sometimes these pets disappear from Andorhal as soon as you enter it because they don't occupy all phases of that place. I've had that problem myself, but can't recall which quests were problematic.
