Valve released the first balance update after the big patch, they've nerfed Glimmer Cape, Familiars, Ursa and buffed Roshan.
The first balance patch for 6.84 has been released; heroes like Gyrocopter, Visage, Undying, Beast Master have received major nerfs from a competitive standpoint. Gyrocopter got his intelligence gained lower, Visage's familiar's hit requirement is now 3 as opposed to 4, Undying's minimum slow and amplification got lowered and his Soul Rip is now more expensive to cast. Centaur Warrunner's Aghanim Upgrade along with Ursa's Enrage has also gotten their values decreased slightly. Queen of Pain's base movespeed was lowered by 5. These tweaks were not much of a surprise since some of these heroes had absurd Pick/Ban Rates; Queen of Pain: 95%, Undying: 86%, Gyrocopter: 74% and so on.
Some of the new items have also been nerfed, namely Glimmer Cape and Silver Edge. On the other hand, Roshan got an armor buff; its armor upgrade has been increased from 1 per 8 minutes to 1.4 per 8 minutes. It'll be interesting to see if the P/B rates of these heroes decrease, it might also have a say in the on-going tournaments such as D2CL and Red Bull Battlegrounds.
