I feel like the many companions really need a reboot in their abilities. Right now the only ones who any real skills/abilities are Erevi, Succubus, Familiar, Oksana/Purifiers, all Goblins, vampires & Oakly. Everyone else just has Heal Minor Wounds.
Gabriel is a veteran Hero, he should have at least Mighty Blow if not some other abilities to show his skill (even if hes a bit rusty). The Giants should have the Swipe ability like Oakly at least & I think Caleah & Liandra should have some Ranger based skills that make them more formidable with a bow zo they are more useful in battle (especially Liandra against the Great Grumpkin). Ziva should also have more divine skills at her disposal (if not on her first run then later if she joins MC she should have some new divine powers near or on par with Erevi because her goddess is now stronger).
The only people I will let pass is Julia, Oliver & Tom because their class is Villager so I dont expect much.
I really hope this changes in the future cos most companions are useless outside of healing & hitting things.
