New Raid target spawn Scenario

[Droodler]

First, I agree with the idea of your post. Server wide repops allow more people in on the action, as guilds have to prioritize their targets. There is one problem, however.

All of these mobs will spawn and be taken out in a matter of a few hours. What will people do for the next 5 days?

I don't think this problem overshadows your idea, and it might even be an advantage for IB/DA to see their families for a few days a week. But it is something to consider.
