Answering a post from a confused gamer, Vyvyanne, QA Community Liaison for NCSoft, sheds some light on rewards and storyarcs and addresses any concerns that things have changed.
Not a change. Storyarcs always worked this way, it just wasn't noticeable until the reward screen was added.
Storyarcs work the same way as villains when it comes to the reward vs. difficulty issue.
You only get enhancements for killing a villain if they con Yellow or higher to you. (sometimes white)
The same is true for storyarcs, if you complete them within one to two levels of recieving them you are rewarded with an enhancement, if you wait until it is easier to complete you will not recieve the enhancement, as the storyarc is no longer considered to be of higher difficulty (yellow con).
