The only thing i can come up with is that a party character must personally inflict damage, maybe even the death blow itself for the party to gain XP. ie, if you summon a creature and it kills something unaided then the party doesnt get the XP for it, i think its the same for traps. Really you should be using traps to weaken a monster as opposed to obliterating it on the spot. This is kind of fair enough really. Traps will trigger the second an enemy turns red, this way it prevents you laying multiple traps and reaping the XP rewards for sitting back and watching the carnage with no physical input yourself.
