@Meddler what do you think of having Darius Q % heal go up with ultimate rank?
This is just a suggestion for when Darius banrate drops and IF he still too strong and may not be useful if you decide to change the heal formula but if you keep it, it could work like that.
Darius Q would have 9% heal max 27% without a point into his ult. then would go up by 1% per point into his ult (10%(max 30% with 1 rank)
11%(max 33% rank 2 ult) 12%(max 36% rank 3 ult)
Could be a passive on his ult explaining it OR in the tooltip of Q
