The main benefits as I see it is that by making the monster stand and cast his abilities a unit is taken out of the game temporarily, however, if you want to stand and fight, you have the option to, every now and again, control which abilities he can get off. No more shielding instant recast? Yes please.

This probably won't happen because Blizzard won't even add a buff icon for the Wizard Familiar skill because they want to keep the interface as little clogged up as possible (so it doesn't get to WoW standards). If they should do anything, they should imo just create casting animations but in my opinion it's not needed.
