Considering most events expire today or tomorrow - it would only make sense. I mean it is in their best interest to keep us interested in the game after all - assuming the level cap is 70 this is going to become exceedingly harder as people will start hitting 70 this/next week.
I am on S17 there are people already lv65 but I am only 57 so it will take me a while to hit 70:'( I don't want a level cap increase in next 2 months to be honest:lol)
