Disagree strongly, this way it'll be easier to get carried. Yes, it is frustrating when you're in group 1, either get a group of friends, a static or pf to clear a9s- then you can farm it easily in raid finder. I'd feel terrible for all those people hoping to get their weekly clears for a11s or 12s in raid finder, knowing that they have and can clear it- but getting held back by people wanting to get carried.

Put the effort into the clearing the raid once, raid finder will help you to get all your future clears if you have no static or lose your static.
