I try to optimize when I start my pugs. I have noticed that the hardest bosses might be better to be started on the weekend or later, even though not too late in the reset because people become itchy. I wonder if some of you have similar ideas on this.
The early days of the reset do seem to have people, however, most of them seem to be low geared or low skilled and most of the effort of the high skilled appears to start in the weekend. Perhaps it's because they failed to attend their guilds' raids.
It also appears that early times in the day are better for pugs. Most people on high gear or skill may be in guild raids late at night or asleep. Ironically, late at night when most guild raids occur, might not be that good for performance btw.
