These jungle changes are going to kill many junglers
You just did changes for tanky junglers, who really have the hardest time in the jungle, usually with slow clears and low sustain. And before that with single target junglers who need gold for items and have pretty slow clears. All of this was basically put on a level playing field with the new ancient golem and lantern/feral flare.
now your going to get rid of them and the only jungle item will be machete and its smite changing upgrades (from their just straight stats for more gold.) Now while i like being able to use smite more strategically and even against other champs, this is going to make things impossible for some junglers. Don't even take into account that your going to make the jungle harder. Naut, Sej, Rammus, maybe even amumu will be out. Voli will struggle. Your basically taking a huge step back and going to S1.
Now while i'd love to get my warwick out again, the jungle items that have been shown at the moment are so lacking that they are going to kill all jungle diversity
