The problem with the constant patching is still an issue for me too. Hoku posted a workaround here:
This works fine, but there really should be a fix for this issue as it’s been over a month and is effecting all Blizzard games, not just Hots.
This isn’t an issue for the Hots technical support posting here to fix, but I’m very surprised this issue has persisted for so long without even an update on when it will be resolved.
