Howdy maggiemay,
I don't swarm as much in Laz as I used to (HC zones generally now). Below are a couple examples from my Wiz and Enc. Hope this helps get you going! It's a lot of fun to take all of F2+C2 in POF, no doubt it's a rush to get 20+ aa in a minute.
Wizzy example:
DPS7=Gelid Rains|95|Cond6
DPS8=Circle of Thunder|95|Cond5
Cond5=${SpawnCount[npc xtarhater radius 35]} >4 && ${Target.Level} <69
Cond6=${SpawnCount[npc xtarhater radius 60]} >4 && ${Target.Level} <69
you can also have some conditions and pop some offensive AA too:
Cond7=${SpawnCount[npc xtarhater radius 60]}>10 && ${Target.Level} <69
Cond8=${Me.AltAbilityReady[Acute Focus of Arcanum]} && ${Spell[Acute Focus of Arcanum].Stacks}
Cond9=${Me.AltAbilityReady[Focus of Arcanum]} && ${Spell[Focus of Arcanum].Stacks}
Cond10=${Cond[7]} && ${Cond[8]}
Cond11=${Cond[7]} && ${Cond[9]}
Enc, to trigger Illusions of Grand:
DPS8=Illusions of Grandeur|97|Cond10
Cond8=${SpawnCount[npc xtarhater radius 60]} >8 && ${Me.AltAbilityReady[Illusions of Grandeur]}
Cond9=${Me.GroupAssistTarget.Named} && ${Me.AltAbilityReady[Illusions of Grandeur]} && ${Target.Level} >69
Cond10=${Cond[8]} || ${Cond[9]}
