I've noticed that svn nexuiz spawns quad at slightly different times now.
And personaly I believe it's not a good idea. And here's why:
Fighting for the quad is a signifitiant part of the game. And knowing when the quad spawns is important to make this fight actually skill-based.
With random quad spawn it becomes more of a luck then skill. Which can be fun also but absolutely ruins the competitive part of the game.
So I'm [s]asking[/s] begging for a fixed time spawn at least on ladder servers.
