Killing Noble when it pops?

[Pan]

We (Omni) got the first noble this AM at a rather unholy hour - we were watching for the spawn and it was our turn in the Wed rotation with Divinity.

Next Noble just spawned - and I was told to leave it up until their nighttime raid. We offered to help kill it and give them the loot.

Is this what we want to do, collectively? Push the timers out until it's convenient for us to hit it?
