why is Ornn so overloaded?

his Kit has way too many things that just can provide his team with so much gold. i mean his passive literally upgrades their items (not sure how powerful that is going to be yet so can't say much on that) on top of that he can shop in lane meaning he basically never has to leave it if he is doing good. and if he can buy pots in lane he basically might as well have a with him at all times because he is gonna be topped off like crazy if your lane isn't super aggressive with him.

His Q i would say is pretty fine and standard however coupled with his E it seems like it will be crazy powerful on him but that seems like a standard ok thing in the long run and not one of his real issues. the fact that his E can destroy terrain though is kind of crazy powerful as it can make or break some champions entire fight or escape potential very easily with a spell that probably won't have much of a cooldown.

His W is probably the most overloaded spell i have seen in the game. it makes him CC immune with a shield and deals %health damage. likely this champ is going to be building tanky so that's an unstoppable wall that can block an entire team's CC (unless you clarify it blocks like 1 spell or something) and still be at like 75% health or something while also likely chunking your team's health for your allies to just pick off now that Ornn has soaked up likely everything that can stop his team from engaging, on top of this it will apply "Brittle" which lets him knock them back. not only does he ignore CC he also deals out CC. on top of this it also makes your allies CC last longer and hit harder... there are so many champions that can just exploit the shit out of this allowing them to mop up teams without any way to likely stop that due to how long the CC might last.
the thought of this ult lasting longer scares the crap out of me

and than his ult like what? it's a ult that applies brittle which makes cc last longer on top of that it can be sent flying back causing knock up and re-applying brittle meaning if your team combos into it with their own CC the enemy can't move for who knows how long and the ult is almost an entire lane wide without mobility that is gonna be so hard to avoid.

Ornn is interesting and cool but man he is so overloaded i fear that when he comes out he is gonna be nerfed into the ground over the series of like 3 or less patches.
