I honestly think Tibbers only feels better because he has a higher base attack-speed (and much faster aa animation), and he has the fury thing which makes him run and attack super fast. Less opportunities for auto attacks being cancelled, which I think confuses A.I. Ivern attacks somebody, Daisy slowly trudged over and raises her arms, someone else hits Ivern, Daisy trudges back over and raises her fists, mid auto Ivern gets out of range of her, she teleports back and bugs out for a bit trying to figure out what happened before trudging over to the target Ivern was targeting, etc....)
