Glad to see your progress and hope it continues to go well.

Awhile back, when theorizing teams that could do OK with the new policies by not requiring "spammy" play that could look like broadcasting/mirroring, either 4Hunters+Healer or Tank+3Hunters+Healer were combos recommended specifically for the reasons you delineated (petattack and auto-shot giving decent DPS).

I think Paladin Tank would be overall better but, between Misdirection, feign death, and not doing true AoE on your DPS you likely can be OK with Druid Tank and 3 Pets.

Would be great to see updates and in particular am interested to see if you are able to clear dungeons at cap (especially Heroics).
