Personally I have 100 points right now, and I know others have many times more. If they included point items in the shop, a lot of people could have just bought gear at level 80, kinda defeating the purpose of the seasonal realm. Don't get me wrong, the coin shop does the same, however items weren't available for coins at the beginning. They could've done the same with points, however like I said people have many saved up and could've just bought all the items they needed instantly for free (server gets no $$$).
