Tier 1 – The best at what they do. Some are the purist of control junglers or the fiercest of gankers and some are versatile enough to do both. Whatever the case these are the best in terms of jungling – they far and beyond exceed several or all aspects of jungling and have an indisputable strength about them.
Tier 2 – These junglers are the strongest after the gods. They usually excel at most of the aspects of jungling and are far and beyond in one or two. They have fewer weaknesses than most other junglers and may have a niche ability unique to them. When you want to excel at jungling – you come to these first.
Tier 3- These junglers are very similar to Tier 2 heroes. They are sosimilar that they’re basically interchangeable and are very capable of competing with tier 2 junglers. The only reason they are in a separate bracket is due to them being not as well rounded or someone above them is their superior mirror. Also for organization purposes.
Tier 4- These junglers are weaker than the other junglers either due tonaturally just not being suitable for the jungle or having to alter theiroptimal builds in order to jungle successfully. At the same time there are others above who are simply miles better and they bring nothing really unique to jungling. They’re usually prone to being dominated by stronger junglers.
Tier 5- A special tier graded differently than the others. The junglers here CAN jungle but they usually have to impact their standard builds in interesting ways in order to successfully do so. Either the impact is minor, but noticeable, or major and could affect them later into the game. Placement is also a bit wishy washy.
