Thank you so much for the suggestion, it is the first time I did a champion concept and the first time I actually wrote something in a wikia. (It was a pain for me xD)

Did what you said, in the passive you have the scailings for the totems, they last until he casts the ability again or if the totem is killed. The cooldowns were long because of two reasons:

Reason 1: Because it is only summoning a totem, it doesn't have to be too much short.

Reason 2: His E is like a Taric's W, you target someone and in a short range every enemy that steps in the range is slowed.

His ult I wanted to do a passive that would give extra stuff to the totems, but I wasn't able to edit it properly so I thought of the area heal xD. I had this idea because on WoW I really like the Shaman class and on Paladins I play (and enjoy a lot) a champion/hero called Grohk that uses a Totem to heal.
