Turns out the confirmation of a delayed patch was all false, as reported a day ago by Tundra Esports' IGL. Valve released Dota 2 patch 7.32d with small but needed changes to surprise fans. It includes nerfs to the hero Marci and the Wraith Pact item.
Seemed like it was going to be a small patch, but Marci's weakened abilities will not let now win more games, like teams did back at TI 11.
Wraith Pact is no longer a required item for every single offlaner. The reduction of damage types means that the magical and pure damage aren't affected by the artifact now. Another hero, Leshrac also received nerfs, with his radius of Split Earth being decreased.
Fans had the chance to play Dota 2 without post-TI updates for 2 months, but now, they need to get used to the current changes. Have a look at the details of the patch on the official website.
