Fyi, there a large number of variables on pull agro in eq. One of those is mob intelligence, undead and animals will typically be flagged to attack the nearest person they enter into melee range of until the tank establishes very solid agro, well beyond what’s normal for a mob flagged to be considered intelligent. You can beat this by invising the group so that your softies aren’t on the mob’s hatelist as it approaches and having the puller fully pass the tank until the mob arrives, and then backing up to melee after the mob is on the tank. Once you get the tank next to the mob with some agro things proceed normally afaik, this is just an initial low agro thing.
Knights can beat this but it’s more of a problem for warriors obviously. Knowing the mob’s intellect rules can inform your pulling/tanking setup, but tbh as a puller/tank, getting the dps slapped in the back of the head every once in a while is a fun thing (less fun if they desperately need to level/gear up and explode into a bloody mist instantly, tho ymmv).
