AP Ivern is Useless ATM
If you came here before down voting because of the title then congratulations on taking out a moment to read this far.
Ivern scales off AP, but he does not have the burst to put that AP to use. He can't Q,W,E,R combo champions to death and he has no escapes for when things get hairy. His movement speed is also incredibly low and he's a big guy, making him a standing target.
An AP Ivern will get one skill, maybe two, off before dying to being collapsed upon by the enemy, especially when they realize how easy it is to kill him. And any AD champ will be able to 2 shot him on their own if he's caught out.
Other than making Daisy slightly less squishy and granting a big shield that doesn't last very long, there's no real reason to build Ivern as an AP champion.
Daisy doesn't even offer much in the way of combat. She has ridiculously slow attack speed and she stops doing anything whenever A, her target dies or B, her target leaves her ranged. Pinging for 1 of 4 allies to do something is hard enough already, why should we be expected to ping for a 5th one to stop going neutral and stay in 1st gear?
His unreliable ultimate is another reason building AP Ivern is a bad idea.
The only build I've seen work on him is a CDR Tank. You keep Ivern alive and you can at least provide long lasting utility to your allies whether they appreciate it or not.
is useless at the moment. Every time I play with or against an Ivern they just feed horrendously and are the central reason the team loses.
Works pretty well for me.
