Forgotten sands - almost swarmed

How busy is the Forgotten Sands area in your experience? I got to the point of being able to do uber runs now and first 3 times, Duriel was always right close to the portal in Forgotten Sands with no other monsters in sight. But last time, the area was crawling with egg laying maggots and phys immune insect swarms, it took me good 20 mins to find Duriel who was tucked away in a distant corner of the map and I had carefully maneuver not to get irreversibly surrounded by the phys immunes, which I wasn't really prepared for, playing a smiter.

Was I just lucky the first 3 times? Or was the last time a fluke? How crowded is the area usually for you?

The area around the Red Portal is usually not busy at all, so if Uber Duriel is there, like it most of the times is, you don't get know how busy the area. But if you go on a trip to find the Uber Duriel you do see how busy the area.
Like I said, most of the times Duriel is just right around the Portal, but once every few runs it likes to play and seek and that's a pain, cause it's pretty good at it.

think i had similar experience most times he was chilling by the tp but once he was quite far away, luckly i had javazon in a party so the trash mobs just vanished

having a hammerdin alt to clear to clear some tough zones or tele to the boss is handy (2 acc req for teleing to boss)
