Excellent point about Thunderwave. I completely brainsneezed that particular power. Have you considered making it chaining, with the requirement that the next target be different than the current one? Something like:
Attack: Intelligence vs Reflex Target: one creature Hit: 1d4 damage. Make a Secondary Attack Secondary Target: one creature other than the previous target Secondary Attack: Intelligence vs Reflex Hit: 1d4 damage.
At level 11, you may make a second Secondary Attack after the first. At level 21, you may make a third Secondary Attack after resolving the second.
So, at the extremes, you could pop 2 guys twice or four guys once. And I'm not sure what you do if there's only one badguy left. Pop the second one on the Fighter and forgo the final one?
