So, I just played Ivern for the first time today...
This character is fantastic. He doesn't do huge amounts of damage, but if he can stick on someone can still pick up some kills. The best thing about him though is how chill he is and how that even spills over to the rest of your team.
There's no more fighting over extra buffs, you just donate them around. I even had both my mid laner and adc say thank you after donating blue/red. Ivern is very balanced from what I'm seeing so far as well (minus the occasional Daisy glitch out).
Looking forward to having a lot of fun with him in the future!
