A small but good change to ritual class would be...

I'm loving the ritualist. But I always let my monster ability run out and don't know how long it is before I pop it again. a nice quality of life change would be to make it have an animation on the hero while active so you can visually see when it runs out and know you need to pop it again instead of always having to look at the bottom of your screen to see if timer is still active. just a thought.

Skill issue.
