Heroes 6 - Discussion

According to the official version, the day-one patch will indeed be released on the first day. The idea is that the version packaged in boxes at the end of September will go on sale on October 13th. This gives them time to fix the balance and minor flaws, and when the game is available to users, they can immediately download the patch. If they don't have a clever, changing link on the server, I will try to upload the patch to ХВ. Otherwise, you can find it yourself, or I will provide a link.

And it's clear from the beta test that they would never have been able to debug it without testers on their side.

The testers didn't really debug anything; they just pointed out obvious things about the town screen, necromancy, healing, etc. The developers could have figured that out themselves. And few people said anything about the balance, as that version was the one that caused the fewest complaints.
