Calling it right now, Ivern's passive is going to get nerfed
I might be a bit premature on this, and might be completely wrong...
Not for jungle Ivern, but for support Ivern, given the fact that at level 1 it takes 10 seconds to "free" a camp, it might completely ruin a junglers day.
Just think about it, it will spawn jungle wars in the enemy jungle. Ivern starts enemy camps, leaves their adc to solo lane, they both get more exp and gold then the enemy team, not only that but screwing the enemy jungle over by taking each camp a little late and then they just dont have anything to get.
Unless the enemy support goes to try and counter Ivern... which then means the enemy support loses EXP the mid laner would probably have to leave lane to help push him out, but that gives the mid laner exp advantage...
Not to mention he can always just freely take his own gromp/krugs if his jungler isnt taking said camp, which gives him an advantage, which means a lot early game.
The counter to this would be playing a super aggro support that can ensure a level 1 kill on the enemy adc but that isnt even fool proof.
His passive might need to be disabled from level 1-3 unless he has smite to help counter this...
But maybe im wrong and just over thinking this...
Just remember he is still on the PBE and we have seen champions concepts nerfed on the PBE before for being too strong, like azir
