In a power point system, there are a few ways to address the spamming of powers that 77M (and myself) are concerned with.
1) Escalate costs for the level of a power. 5th level daily costs more to use than a 1st level one. You have to track a bit more, but it can do the job.
2) First use is free, then you have to pay. You can use each power you have once without cost, the subsequent ones costs X amount. This is more of a bandaid, you'll still see spamming with occasional, "I'll use my 'free power' right now.
3) Each use of a power costs more than the last. This is the most effective way to prevent spamming, but its also the most complicated to track.
