That depends on your situation. I'm getting the anniversary antique, Hecate's avatar, the muse customer selector, and DIV2 resources. I don't really need the other resources. Just purchase what you need. If your needs are met, purchase what you want.
What happens if I didn't choose any of the recommended heroes mentioned in the video, will I be able to choose them later on, or is this event specific to the 3 year anniversary?
IGG plans to activate the Leap of Faith event at every update, so there will be more chances to pick another three heroes of your choice. For the ones you chose this time, I guess you have to just own it.
