A realistic ending to such a plague is the mutation of the disease organism into a more benign form. This can happen in CoE, but could not happen in WoW.
Also, I would hope that CoE would have variable rates of susceptibility across the populations, without specific favoritism toward experienced combatants. Lack of character levels will help a lot, since except for specific tribal resistances, there will be no exceptionally resistant individuals.
If such an event happened in CoE, I would expect players to behave very similarly to the way players behaved in WoW.Posted By Johan Housel at 3:56 PM - Fri Mar 16 2018
... Primarily we're concerned with the Dras and our customs processing gate includes the Center for Dras Control where we process and do medical checks; that section of the city is also where the Dras will primarily take residency in the city and offer their specialized goods and services as well as staff the processing point for the 'riskier' visitors.
There is no clear evidence yet that Dras will be disease carriers, but this is a wise precaution. Even if Dras turn out not to be disease carriers, the precautions are a good spin on plausible beliefs of non-Dras citizens.
