I played Ivern a lot with Rengar and Caits and rengar+ Caits. But to be fair Ivern is just to weak (base stats)
What i want to say is yeah his q is good but that is where it ends.
His w is a complete faliure of a spell
(cait passiv and rengar passiv are fine but its not good)
The problem with this is that you force your adc or jungler to play a champ.
( that is not good in this game / the player is not that good on that champ)
Your passiv is way to locked on one job that makes it hard to use
Your e is a nightmare you cant get this shield good, the problem is that it does all jobs but none good.
(you e a mele and your shield is to weak to take all the damage / you e a ranged and your slow is usless)
The r is a the cherry on top of the cream, a ultimate should have a big impact its "ULTIMATE"
if you play ivern you got your Mate and its yeah like a bad version of tibbas.
(this Ult provieds really nothing in the first 2-2,5 sec of a fight and yeah that are the most important sec`s of a fight in botlane since the low base stats of a adc)
His base stats are weak like a lulu but lulus job is not to be in the Frontline
so what is Iverns roll as a Supp ?
To be a enchanter nope he has just one spell for that roll.
Is he a Mage nope he has a spell like it but not the right damage nubbers.
And he is not a Tank so what do you pick him for?
Thats right as 2nd jungler, that is where he is good, but then you shouldn`t play him on botlane.
Play him in the top against tanks that lack wave clear.
and for you littel klyde dont be like that, i can see that you are mentally challenged so just get some help thy!
