Hey just going to through something out there, something that is written with a bold "warning" at the top of the page you linked:
Warning: PBE Content is tentative and iterative - what you see may not reflect what eventually gets pushed to live servers! Manage your expectations accordingly. )
If something is on the PBE, that doesn't mean it's going to live. Also, read the section on the jungle changes in today's post. They clear up a few things.
Here's Fearless with a few comments on all the recent jungle changes that have been going on and off the PBE over the last several updates:
"Hey all,
Way over due on this. As you've all noticed, we've been trying some very quick iteration cycles on the jungle camps to reduce the benefit of bot lanes poaching jungle camps at level one. The two iterations that were tested on PBE were Krug and Gromp having their own buffs until smote, and after that, a buff to the base stats of the camps, with machete buffed to compensate.
The results of our testing in both cases led us to believe that the impact on the jungler from these changes was much too high, and in the second set of changes, might not have even pushed the lanes away from the level one poaching.
The end result is that we aren't happy with the solutions so far, but we've been really happy to throw changes at PBE at a rapid clip, and be able to get your reactions and play testing. It's been incredibly useful for us to work at this pace and get the very quick feedback. Mainly wanted to do this post to say we're likely to keep this up for this project, as well as others in the future. Thanks everyone for the testing time and the thoughtful feedback!"
He continued:
"Generally looking to not do anything too heavy handed. One of the reasons we keep having similar issues with poaching is because we do very specific, heavy handed changes, and when we have to fix another part of the game that changes some of the details, very specific fixes break down.
We're currently wondering if the cost of leaving the lane alone is just too low. Making the cost of poaching higher seems to be misguided, as we've never really been able to fix poaching this way before, we've just made it impossible (by making the camps spawn so late its not an option). We're almost out of time this year, so there's not likely going to be any more changes going to the PBE in 2014, but we'll continue to test some options internally. The explorations for now will likely be seeing if we can make the cost of leaving the lane higher if the other lane takes action, to offer more counter-play to poaching."
