It can be a good up for Grohk, because after deploy his totem he need to wait 15s before deploy another one. Imagine if he can redeploy his totem every 3s, first he deploy it on the point and 3s after near him and the Damage.
With this change, I will increase the basic radius of 20% and change the card which increase the radius by a card which increase the deploy range of 20|20 units.
