Not Enough Missions

EDIT: I now know the missions are weekly, my bad!

I've been genuinely loving the missions system. However, what I don't like is having to pay for extra missions. With the past events (excluding the SG event) they've been pretty good. Do some missions and earn some cool rewards! At least enough to get cool orbs that give legacy skins. But this one, I get 35 tokens. All I can get is some essence and key fragments which I got on a regular basis. It also left me with a mission that I can't complete unless I pay for more missions.

Really liked the missions system until it became pay to win.
