Goodness - you folks have been chatty lately, haven't you.
Other changes of interest in the PBE
Kass is taking a nerf again to his ult - He's doing less damage at later levels, but getting better ap scaling (.5 to .8)... it's kind of a buff. For instance, if you have 300 ap, you'd to 150 added damage before. Now you'd do 240 dmg (increase of 90) - But, they are reducing the base dmg + the bonus you get from subsequent casts of his ult and the 1st cast of his ult (was 60/90/120 now is 60/70/80). The numbers work out so that its an early game buff, a mid game nerf, and a strong late game with added dmg. In short, its really not going to make a heck of alot of difference imo outside of late game. He could carry a bit harder late game now.
zigg's satchel charge is getting a some additional cdr - won't really make any difference, but it was way too high at early levels anyway, so that's slightly better, but still crap
Urgot's the interesting 1 - Base damage of acid hunter going to 50/80/110/140/170 from 10/40/70/100/130. I doubt this works out as a buff as they likely are changing the formula on how the damage is calculated. Probably instead of basing the bonus on total AD, its likely just bonus ad. This is probably to discourage folks (read - everyone) from building more tanky items on him as his AD will fall off some. They are also increasing the CD on corrosive charge, so this is all pretty much a nerf imo.
gp gets a qol buff. Parley refunds half of the mana cost when it scores a killing blow now. This will help gp's sustain if used as a jungler but mostly help top lane as he get's a gold bonus for last hitting with parley as well.
Akali restores more energy when busting a mark of the assassin - this is a nice buff early/mid
Malph = nerf. Ground slam now gives AS bonus for 3 seconds instead of 4 and this scales off 30% of armor instead of 50%. This will hurt jungle malph + top lane malph a bit
orianna - another buff. AP ratio changed on command: attack to .05 from .04. Not huge, but with the really low cd now, that coudl add up.
heart of gold gives 200 hp instead of 250 (woo)
philo stone health regen reduced to 3 from 3.6
