I didn't see this mentioned earlier, but timing can be very important to finding a static as well. We are in a bit of a content lull right now, and a lot of groups are fairly solidified. The best time to look for a static is the 2 weeks prior through the 2 weeks after a new raid tier comes out, as that is when players tend to shuffle around the most. So if things don't go well right now, do your best to cap your gear on whatever class you want to raid on, and try again when Alex part 3 hits.
