MAJOR UNAVOIDABLE IVERN ISSUE
Ivern will inherently be better on the blue side of the map. He can share red buff with his adc and blue buff with his mid laner with no problem. However, Ivern on the red side will not be able to do this. Because top laners can't normally make use of red buff as well as adcs can, I believe that there will be a big win rate discrepency between red and blue side Ivern, and I'm not sure there's anything that can be done to rectify the issue. The champ's broken before it even comes out.
Also. Caitlyn is sort of the same way - Red side Cait can hide traps next to blue side tower - she puts them in a place that takes advantage of camera angle to make it impossible to see. A Caitlyn on red side can't take advantage of the hidden traps. I have no knowledge about whether or not the winrates for the two are significantly different (even half a percent), but it's the same concept.
Edit: Even if you don't agree with me that bot lane can best use it, it doesn't really matter. If top can use it significantly better than bot, the point still stands except that the opposite Ivern is better.
Also. How do I get so many upvotes with all my comments saying I'm not right? xD
- Red buff? 0w0 fuck yeh, now I can actually win 1v1s
- Red buff? meh, oh well, a bit more dmg to my burst and slow to my 3 dashes can't hurt now, can it :D
- Hmmm. DO I LOOK LIKE I NEED YOUR RED? for the notice, yes I do, I'm full red. (Honestly a Darius with Red would most likely have full top lane dominance until it expires)
- I got 3 slows in my kit, but no true damage. Bringing on boys.
- FOR FRENCH, for glory. And for MORE TRUE DAMAGE AND EASIER ULT KILLS (if targets moves slower, its easier to position a vital strike)
- You know my Q counts as an Auto attack right? And your know my QE counts as an AoE auto attack right?
- GNAAAARDADADADADADADA. (as a top laner that gets a huge power spike on fronzen mallet, imagine if he gets a similar effect on ~7-8 minutes in the game).
