For EM you need to know when to quit for some nights especially for the newer players who don't have gems like some of us do. They also need to know from us seasoned players which birds are worth going after. There is not point for tickets strapped new players to hatch in events with "Collector birds". this week Lady B and Dedsw1n is the prime example. Chuck you need few to make the team powerful, same goes with Matilda. Terence and Red not so much. Bomb has its use for certain event levels layout.
