In truth, Sylvanas did not care in the slightest whether these Quilboar lived or died. Yu Lin Bloodhawk wanted them alive, so she would give him a herd of living Quilboar, just as she had done during the attack on Jintha'Alor.
Sylvanas also knew that capturing these Quilboar alive was far harder than simply killing them. Still, she believed it should pose little difficulty for the High Elf forces as they were now. It would take hardly any extra effort.
To be honest, Sylvanas did not entirely agree with Yu Lin Bloodhawk's order to capture the Quilboar alive. But since he had given the order, everyone should carry it out immediately, rather than find excuses, much less disobey. This was an army, not a marketplace, and more than anything, she hoped Yu Lin Bloodhawk would truly grow into a competent commanding officer.
What made a competent military commander was not a head full of schemes and military theory, but the ability to command his troops and ensure that orders were obeyed without question.
In Sylvanas's eyes, Yu Lin Bloodhawk was full of devious tricks, and his ideas were often far nastier than her own. She therefore had no fear of him coming off worse in battle.
After his years of effort, Sylvanas also believed Yu Lin Bloodhawk had earned a decent reputation within the army. Yet he still lacked maturity when it came to commanding troops in actual combat.
The captain of the City Lord's Household Guard had just provided a telling example: even after Yu Lin Bloodhawk issued his order, the captain still wanted to question it. Sylvanas therefore believed Yu Lin Bloodhawk needed more practice in this respect.
With Sylvanas's orders delivered, the High Elf troops had to go to the extra trouble, whether they liked it or
