I find season 3 jungle changes bad. For the first 2 weeks everyone will be yelling at the junglers who aren't holding their hand for once. Also, with the harder packs all the low level accounts won't be able to jungle with any effectiveness expect MAYBE WW. Still, with these buffs it's nearly back to S1 jungle where very few people could do it well so we're going to have even more failures in the jungle.
I'm excited about the challenge, but they've stated some junglers are not going to be good like EVEYLNN. Riot has even said she lost her niche in the jungle, so just play her mid. Otherwise I'm interested in the changes.
