I play it every week. Not going to be on ProtonDB since it's a Blizzard/Activision title, but the Lutris installation for it/Battle.net works fine for me. Occationally Blizzard will push an update to Battle.net that'll break the ability to play their games, usually fixed by a reinstall, and Blizzard's servers are held together by duct tape some times, but all that aside yea it plays just fine
