I just realized the purpose of the Garen jungle regen buff @ level 11

I have been wracking my mind trying to figure out what the purpose of the level 11 buff to Garen's regen was -- where only epic monsters will turn it off. I mean, the late access to the buff means it is not intended to help someone be a Garen jungle, yet there it is. Then I realized that the purpose is to allow Garen to run through the jungle when he has Sunfire Cape on without turning off his regen passive every time he runs past a monster pack.
It's actually a really smart buff. Kudos to Riot.
's inability to keep the form he wants 24/7 is a meaningful downside because it's one that he and his enemies can play around, and one that enriches gameplay.
was attacking, it wouldn't remove any interaction with Blitz's enemies but still offer similar gameplay. Similarly, a toggle on Sunfire Cape would help in that respect. If there has to be a tradeoff, it should be one that doesn't punish the player for buying the item in the first place.
instead of
Pillar of Ice won't shut off Perseverance. Maybe at Level 6 or 16?
