Blizzard does not take game advice or suggestions from the Bug report forum See: How to Write a Good Bug Report
Feedback is NOT a bug. Anything related to feedback, class balance, boss suggestions, etc. belongs in another forum.
If you want someone at blizzard (with the authority to change it) to be able to see your suggestion, then this thread needs to be moved to the General Discussion Forums.

The fact that Familiars also do not benefit from Enforcer Gem is further proof that Familiars are not counted as pets and that this is an intended interaction, not proof that there are multiple bugs with Familiars.
