After you defeat Ick & Krick (Second boss in PoS) have everyone mount up and run past first 2 trash mob packs that spawn after you defeat the boss. They wont aggro for first ~10 seconds so you can safely skip them. If someone fails to get past the 2 packs (in worst case Tank or Healer) you will have to kill this 2 packs or summon if you have a Warlock.
Then you can hug the wall to the right to skip 3rd pack.
I'll update this thread with pictures tomorrow because I'm saved for PoS today...
I'm pretty sure this isnt a repost, because I searched using: Pit of Saron, Pit of Saron Trash, Pit of Saron Pack, Pit of Saron Skip etc. with no results.
