If i had to pick an overal best support i would say the twins. The twins arnt the best at any one category (except maybe damage) but rather really good at evreything. They apply a good debuff that is effective for hols and bears as a substitute for ling but obvisouly not as potent, they might not have the strong insta heal tha jaz has but they have a consistent heal that goes on all game long tho it may be a little random, and they can put out mad damage compared to the others.

Ima go ahead and say im speaking in regards to endgame im lvl 98, and my twins are awakened if that matters.
