It also encourages collection, If everything was always avalable there would be some people who would only ever get what is thought of as the most overpowered frames. But if you say "hey those arn't avalable at the moment but these ones are...for a limted time!" They will farm them then and be sad if they dont compleate it in the time limited, where as if it was always avalable they might never think twice about some frames.

Its annoying but clever and actually helps sustain the game longer.
