I'm a F2P player and have to spend a lot of time collecting rubies. With a bit of luck, I can buy the event pass this weekend for 700 rubies, but then I'll have to rely on gameplay. With limited protection against op turrets, I have little chance of achieving good results and completing the missions. With a bit of luck, I can get 10-12 ice coins. So, I'm wondering if this event is suitable for me to participate in.
