Dota 2 patch 7.40 delivered an aggressive balance patch in terms of balance, item overhauls, and reworks that reshaped several heroes. Some heroes received a makeover to their full kit, some abilities were restructured, while others received a small, but meaningful addition to round out their abilities.
After some time with the patch, the community has adjusted to the changes, ironing out their quirks while experimenting with the most optimal build. As of Patch 7.40b, these are the most successful hero reworks in Dota 2.
Valve is back with another rendition of conceptually ruining Brewmaster.
