I have a page which lists 15 news briefly, and if you click on one of them, you can read the whole article.
Right now I'm using CollectionPage (You can see that here: https://search.google.com/structured-data/testing-tool/u/0/#url=https%3A%2F%2Fhearthstonehungary.hu%2Fnode).

I've been using this for awhile, but now I started to wonder, that this is maybe bad practice.

Is that okay here? Or should I use NewsArticle (I use that when you read the whole article), or something entirely different?
