As was explained earlier, regen/healing will draw aggro to you regardless of where you're standing. (Including MP/TP regen from AST's cards, if I remember correctly.)

So there are two elements to dealing with this:

1. Never cast Regen pre-emptively - wait until the tank has the attention of all enemies and their names have turned red. Same for healing spells. Or if you really need to heal them, be aware that any yellow-named enemies will be drawn away from the tank by it.

2. If there is a "leftover" regen still active from the previous fight, and the tank is approaching a new group of enemies... stay close to them! They will go for you as soon as the tank pulls them, so if you stay near the tank, the tank won't have to chase after the enemies when they go off in different direction to what was wxpected.
