I don't think this thread demonstrates that because I don't think that even a majority of the people posting in this thread have played epic tier. Of those who have, I don't think that a majority of them have played more than a handful of sessions.But anyone can complain about the far, far more important issue: that the resulting numbers don't result in a good experience playing at the table. In fact, I believe this entire thread demonstrates that players/DMs are able to spot issues with the resulting numbers for opponents and figure out that there's a problem.
