Regarding Kog'Maw changes on the PBE
For those of you who don't watch Surrenderat20 -
Kog'Maw Attack speed growth increased to 3 from 1.5
Caustic Spittle (Q) Armor and Magic resist reduction increased to 20/25/30/35/40% from 12/16/20/24/28% Mana cost reduced to 40 at all ranks from 60
Bio-Arcane Barrage (W) No longer grants passive 15/20/25/30/35/40% attack speed. Now also deals 5/10/15/20/25 flat magic damage while active.
Living Artillery (R) Duration between subsequent shots lowered to 6 from 10.
Without hardcore doing math, checking the break even point, this looks really good. Should weaken his early-mid game strength, and let him scale well into late game. Nice buffs to AP Kog'maw as well. It looks like this'll keep him from being pick/ban, but he might be able to challenge Lucian / Ezreal. Assuming nothing incredibly broken happens, this looks like it'll balance out Kog'maw.
