Perhaps communication was the wrong word. But crotas end looks/feels more difficult. If someone dies during Templar or Atheon it's not as big as an issue then when facing Crota. With crota everyone needs to coordinate a push at the exact time. Because a death brings the over soul and crota himself is down for a very short time. With atheon deaths meant nothing for warlocks during the buff and all people had to do was unload. I can't put it in the right words. Vog looks more detailed but feels very simple. CE is the opposite.
