Even though the title says Companion’s Might is bugged – it’s not really the trait which is.
It’s all new HoT pets (new breeds, Tiger is not included in this bug) that do not have auto-attacks specified as auto-attacks.
For this reason, Companion’s Might does not recognize their abilities to be a subject for trigger.
All new HoT pet Breeds including Smoke Scale, Bristleback, Electric Wyvern and Fire Wyvern need to have their basic attacks coded to be specified as such.
Tigers use the same spell ID as former felines that had their attacks coded so Tigers are excluded from this bug.
