For Patch 11.9, changes to Deadman's Plate and other items changed the placing of some junglers. Taking into consideration patch notes, nerfs, buffs, and win rates, this is the tier list for the most recent patch.
AP Assassins like Elise, Evelynn, and Diana have been really strong this patch. Kayn's Rhaast form received a buff, which is what landed him a spot in this tier. Other fighters like Hecarim, Udyr, and Xin Zhao have had good win rates in this patch.
- Master Yi
Kindred was recently buffed, and their cooldown has been decreased for Dance of Arrows while the damage has gone up. This will make clearing easier, and champions like Master Yi and Warwick who have kits that help them in the early stages are also on this tier list.
Most of the champions in this spot can be built like tanks, but due to the Deadman's Plate nerf their role is more of a juggernaut one. Initiation for Vi or Rengar is difficult, as they fare better when prioritizing one (or two) squishy targets while Wukong and Trundle have crowd control abilities to help them engage.
The assassin meta makes it difficult for squishy champions like Teemo and Zyra (during the early phases of the game in particular) to ensure ganks to help their allies. While it is not impossible, it is more difficult (especially against specific match-ups). Not to mention that the numbers of these junglers are not in their favor.
