Outdated info in Hall of the Novice

[Gordita]

The Hall of the Novice also tries to teach tanks in one of the exercises to separate groupings of enemies from the rest (like the mammets from the other types of enemies) and kill them piece by piece like that.

However, such a tactic doesn't even work in ARR dungeons, let alone more recent ones. The enemies in a pack will just aggro together anyway.

Not to mention that isn't the preferred or more efficient method that most players/tanks do (pulling everything they can from to wall to wall).

There's also the one where they say to use single target abilities on a pack of 3 mobs which is big no-no
