S2 knows about the Mac sound problem, that's all we can do here, we can't fix it ourselves. Reposting about problems doesn't help.
Many computers can handle the amount of resources that HoN loads after each consecutive game. This is HoN's way of decreasing load times, not making you wait as long.
Where else would you go when someone doesn't connect to MM?
I surely hope the people who are working on alt avatars and new heroes arent working on sound problems with the Mac client.
S2 is more than 2 people. There are different people working on different parts of the game please be patient.
