Alliance on my server usually had 4 full raid groups anywhere close to peak time. Horde only has 3, and they only have 18-32 people in each :/

This annoys me. It turns WG into another battle ground. I am curious to see how they are going to do groups? 100 people is 2 1/2 raids. are they going to force people into that? Are they going to change how the quests work?
