Have you been holding out on Warcraft Rumble until it came to PC? You may not have to wait too much longer, as Blizzard appears to be testing the mobile battler with a Windows client.
This news comes from Wowhead, which noted that the latest technical test on the Battle.net app involved a Windows version — which is a first for this game. It should be noted that while this is a strong indication of a PC version, such an announcement has yet to be made by the studio.
Warcraft Rumble recently pumped out Season 4 with the Witch Doctor troop, two new emotes, and better daily rewards.
