Arena Balance Update - Demon Hunter & Priest To Get Weaker
Blizzard has announced on Reddit that they are deploying some micro-adjustments to the Arena mode.
Priest and Demon Hunter card appearance should be decreased, while other classes should stabilize closer to a 50% winrate.
Quote from Blizzard
We are currently deploying a hotfix (17.0.3) that will make some minor adjustments to card offering rates in Arena. These changes update the appearance rate of cards to ensure class balance remains close to the ideal 50% win-rate. Specifically, the win-rates of Demon Hunter and Priest should now decrease and the win-rates of the rest of the classes should now increase.
This hotfix will take place on the server-side, so you will not have to download anything.
