Xypherous Shares and Explains PBE changes.

For those of you who've been curious, Associate Technical Designer Xypherous recently posted a thorough writeup of the changes appearing in the Public Beta Environment, as well as the team's rationale behind them, on the Riot forums. A couple of items have experienced changes meant to adjust functions, perhaps most notably the Blade of the Ruined King:

"Recipe: Cutlass + Dagger + Dagger + 500 Gold = 2700 Gold total from 2850 Gold on live.

* 45 AD –> 30 AD
* 0% AS –> 40% AS
* 10% LS –> 0% LS
* Passive now heals you for 30% of your total attack damage, rather than 50% of the damage dealt. This is essentially premitigation lifesteal.
* Active slow/speed duration is now 4 seconds from 2 seconds.
* Active now deals 100 + 10% of the targets maximum life – serving as an execute or a wind-up peel
* Range increased to 550 from 400. 

Numbers still need further tuning.

So our problems with the previous iteration of the PBE BoRK was that it still suffered from a number of cross-purposes. This version is most likely way too mathy to be entirely elegant – ideally we'd find a more elegant phrasing of it – but this is kind of the sledgehammer approach. We'll probably try to find ways to refine it."

Multiple users have expressed concern that this may be too much of a buff; bear in mind that these are PBE statistics. Alterations have been made to a handful of champions as well, including a general attack speed gain per level improvement for Vayne, Tristana, and Ashe.
