If you have been vaccinated, then the current strains are about as deadly as the flu. We still need to keep ready for new strains and for sudden surges that can quickly overwhelm a single location’s health care capacity. This is true of influenza as well, a new strain hitting a small contained community can cause issues.
I played Dauntless hardcore in the beta. My team and I really enjoyed it and it was going to great but it went to Epic we never gave it another thought. A real pity because the combat was fun. IDK how it evolved but the chainblade started out really enjoyable.
