No its the same as IWD1 and baulders gate. I like to make a party member invisible by either spells or hide in shadows and summon some undead. I walk up with the summons + invisible character to some enemies and the enemies will go strait for the summons since its the only thing they can see. I then have the invisible character run away while every spell caster with an AOE spell casts it where the enemies are bunched up around the skeletons. This makes it very easy to get off AOE spells easily.
