Jungle Tanks Suffering?
Is it just me, or are there no tanks who can jungle with much success right now? At the beginning of the season I suddenly started losing a lot taking the likes Maokai and Sion into the jungle, and finally peeked the winrates and nearly every jungle tank is doing poorly. This isn't some injustice, but it does bother me a little that top lane is now the only truly viable place to put a full on tank. Rammus is hanging in there thanks to 3+ ad comps, but he still does better top lane. Meanwhile these guys are frankly not able to do much in the role.

Now I'll admit that perhaps before season 5 jungle tanks were uncommon and I simply didn't see that. I only really got into ranked at the end of S4 and early 5 so I experienced the tank meta for the most part.
still works well, I go mostly tank on her.
When I look at these junglers, only one of them was nerfed due to their synergy with 5.5 Cinderhulk (Ekko). Now that Cinderhulk is the weakest jungle enchant, the best tank junglers are tanks who build a better enchant.
