I believe when a level 70 is in the group, it is set to Legacy Loot (can get any drop from bosses, not just class/spec specific).
Also, the 70 stays outside, while the low level guy does the dungeon. This drops 2 items per boss instead of 1.
It's common to see top-level players farming World of Darkness (WOD) content without carrying others for a few reasons:
Efficiency: High-level players often have specific strategies and gear that maximize their farming efficiency. Bringing others along might slow down the process or complicate the run.
Reward Optimization: Players focused on farming usually aim to maximize their rewards, and running content solo or with a coordinated group of similarly geared players ensures they get the most out of each run.
Control: By running WOD with familiar faces or solo, players can control the pace and execution of the runs, reducing the risk of mistakes and ensuring smoother runs.
Challenge and Skill: High-level players might enjoy the challenge and test their skills by tackling the content on their own or with a group of similarly skilled players.
