I've so far mostly relied on level 1s for BFA WQs and have otherwise used the purple training stones on a handful of pets -- ones gotten for having a level 3 garrison on a number of alts. I just did my first 3 legion WQs and got pretty lucky managing to do them with 3 of my only 9 level 25s - boneshard, ikky and lil bling - that were recommended for strategies I struggled with otherwise but I don't imagine that luck will hold out long.
I see that people have crafted strategies to even knock out the world quests with every pet type so I'm wondering if there's a strategy to knock them all out with as few pets as possible. any and all help would be greatly appreciated, thank you.
edit: so in my experience the favored pets tend to involve a combination of DoT and debuff, lil bling's inflation + make it rain, flock or hunting party and black claw. is anyone perhaps aware of these sorts of combinations for each pet type?
