Yea that is becuase before this race got them randomly vs requiring an actual kill. This is a balancing change to make leveling this race harder as it was previously the easiest race to max out. This is one of the few cases where a race is being balanced from launch. Some of the other undeveloped races may also incur changes as needed in order to work out balancing problems that were never addressed prior. However I think it is important to note that this is a minor balance change when you consider this race overall compared to the others, even the ones that have not been released yet.
