I see nothing wrong with it. Especially the part about the unwilling sacrifice of others. That's what the majority of people are for and that's how they're used.
I honestly call this a personal problem. Queue with 7 others and problem solved. When you're able to make 24 man groups in time, 90% of this whining will go away.
As a Lawful Evil Sociopath (both in game and real life) who only does things because I benefit from its completion, why would I ask myself the intent of a system I have already chosen to manipulate for personal gain?
