I dont partake anymore because I already know that I am going to get mugged - its like walking through the town centre wearing nothing but a Rolex - you are inviting disaster lol.

This latest fusion event is a classic example. You might be tempted to purchase 100 energy - but then you will get a cool down that means you will miss out on the energy that you get automatically over time.

I guess these events are okay if you have unlimited money to burn though.
