First of all i know this is kind of a repost but the i diddnt saw any without the boss.
Easy pit of saron rep farming, Without the boss.
1 : Go straight to the last boss, enraged it and just few seconds before combat starts, teleport out.
2 : When you get the message combat ended after xx seconds, teleport in.
3 : walk to the boss again now you see the wave of adds still coming but you dont have to tank the boss also
4 : So this means less damage less healing needed
5 : you can even do this afk.
6 : Profit
and again i know its a repost but this way is much more easy.
Happy farming
