I'm also thinking something along the lines of a possible, realistic family buff, that's not crazy OP or does damage outright, but more of a musing about unities that you think are not currently covered, and could make a nice niche family ability.
With MOP we have become even more versatile with pets now bringing Spell haste, Spell power, Battle Rez, AOE stuns and even petrify. Fantastic new family abilities, even if they have been a little borrowed from other classes, the diversity is awesome!
At times I'm left thinking, Now that could be cool if I had a pet that could do that! That could make a rather nifty cross over into a Family ability.
These are some of mine that pop up from time to time.
(these don't have to belong to any family in particular, but can still lean towards some more than others)
Death Grip/Web Pull
Similar to a death grip, but have a "Web Grip" instead. This could be similar to the Carrion Spinners ability in Naxxramas that used to pull your tank (or the 1st to engage) into the spider packs.
Smoke Bomb/Dust Storm
Similar to a Rogues smoke bomb, but could be a shorter duration and maybe on a longer cooldown?
Fear/Terrorize
Similar to a good old Warlock/Priest/Warrior fear. Again could be on a longer cooldown and shorter duration for balance.
Intercept/Safeguard
Have the option on getting our intercept back that our Tenacity pets used to have, even if it's though a family ability?
Cleanse/Absolve
We have a pet that can heal, what about a pet that could cleanse? Again cooldown dependent to make it balanced, but being able cleanse or dispel oneself could be super helpful at times in pve, pvp, solo etc.
Has anyone else ever seen something, or thought of an ability that left them thinking, now THAT would make a niffty pet ability! Please share, you never know who may see our threads
