Action Points

Is anyone else annoyed that you can only spend one action point an encounter? This means there's really no reason to accumulate them. Once you have two, you can use one during the current encounter, one during the next encounter, and you'll still have one for the following encounter. If you don't need to use one during any of those three encounters, you're set for the next two. At this rate, why didn't they just say that you get a free additional action for each encounter? The only difference that really matters is that you're penalized if you take two encounters in succession. It seems like the game would want to encourage you to take more encounters during the day. After all, that's why there's healing surges, etc.
