I’ve spent over 4 years learning the game and I still prefer Source over 1.6. Its honestly not that much harder to learn or play, you just have to learn not to shoot through freaking walls, how hard is that? 
Either way, less tournaments would probably be a good idea. Cycle out some of the less popular games and put in the more popular. Take out the 1.6 Custom tournament and you would have another hour or so at least dedicated for Halo. Move the Halo tournament up or dedicate more time to free-play, it doesn’t really matter. The tournaments were generally, in at least my opinion, well run and finished well within time constraints. Once the tournaments got underway then there was no issue finishing up in the alotted time-frame. As Kuros said earlier, a lot of time was spent/wasted getting people set up to play the games. If people had gotten there earlier or asked earlier to get the games installed, etc then that problem would not have arisen.
