The statistics and abilities now scale in another way - the current value is increased by 4% each level (i. e. Base - 100, Level 1 - 104, Level 2 - 108, Level 3 - 112, Level 4 - 117, Level 5 - 122), so that's why I've changed the numbers here and didn't add any per level values, however I've added values at level 30.
Also, I've changed the Tier 7 Talent The Greatest Voodoo to make it useful insead of making it a joke. It's just like noone would use this ultimate to transform some Mercenaries, and the new one talent will bring even more utility, as it's job of Vol'Jin.
