No, I don't usually hype about a new champion like I am about Ivern.
Azir had the potential to warp the meta, but that part of his kit was removed quickly in beta.
Aurelion Sol had no chance of changing the meta.
Taliyah had no chance of changing the meta.
Yasuo and Braum, in fact, DID NOT CHANGE THE META! Yasuo and Braum both have not affected the meta really in any way except for Braum making Lucian a more popular pick.
With Ivern, entirely new game strategies are viable through his bushes and Q, making bush based champions and Juggernauts much more viable! Champions that were previously limited by mobility now have a way around it and, while that may be scary,it has counterplay since it is single target and relies on ANOTHER champion to hit a skill shot to make it happen. His Passive also makes sharing Red with Bottom in the early game a POSSIBILITY! That's super meta changing since Red Buff is incredibly powerful early game and makes champions that rely on attack speed and/or would benefit from it's slow much better in the meta! Ivern has HUGE potential to change the meta. Why? Well there is one main reason why.
HIS OUTPUTS ARE DIFFERENT!
Ivern does not just deal damage, CC enemies, and/or shield/heal allies. No, he can modify vision, donate buffs, and grants other champions dashes. That's a big thing that no other champion in the past has allowed you to do. Sure, Kalista had potential to give allies a dash, but it was always limited to her Black Spear partner. This has no limit and it allows many champions to be viable, especially in the LCS.
