With the new jungle you just gave blue side yet another advantage
Red buff restores health when smitten and gives a health restore passive. Blue buff restores mana when smitten and gives a mana restore passive.
The majority(if not all) of the junglers in the current state need a strong leash to get things going, the least will come from the bottom side due to convenience and strength in numbers.
This means that blue side jungler has a much higher advantage when it comes to invading right after or even at simply keeping on going towards clearing another camp.
