I have lost an insane amount of elo recently trying to Master Sparrow. How much? I don't want to talk about it. (It's that bad)

So noticing on Agora that my highest win rate hero is Khaimera, I thought I'd play a few Khaimera games just for fun. I don't even really like him. But hey, statistically speaking, the way I play works with him.

And I've noticed. The jungle is insanely strong! I realise that I am playing way below my regular elo due to my attempts to master Sparrow. But when playing against lower skilled players it is far too easy to abuse wards, invade their jungle, annihilate mids and carries.

I can regularly pick up jungle buff and pick off people trying to teleport back to base. Even if they're behind 2 towers. And I sort of feel like I shouldn't be able to get away with what I'm doing.

I can carry so much harder with a jungle Khaimera than I can with a Sparrow... And that's really confusing me.

I also know that the game isn't finished. And abusable strats won't work once more heroes exist to counter strong playstyles. But does anyone else feel like they can do too much from the jungle? Is it just the elo difference? Or am I just having a good day?
