Not so sure on that.

Suvega has a post floating around for WotLK, which is boxer friendly.

For collections, I generally decide if the time is worth the reward.
The reward doesn't necessarily have to even be a reward.
If this collection is part of a chain, which is a lot of experience or multiple easy kills afterwards, it might be worthwhile.
Generally, I'll lead with one, until they're done and then switch to a new lead.
I'll always target the corpse with everyone, and interact initially -- to see if everyone can loot.

Most collections (3 in 4) I skip.
But there are plenty I do too.
