Collecting the normal shards can be done in 20 minutes. Getting the 7 kills for the agonarch rune takes 5 minutes per day for 7 days. You can get 4 or 5 in the raid. You get 1 every week from the tier 3 CoO rune. That's 10 minutes, once a week. You get 3 from tier 2 CoO. That's about 20 minutes. Even if you only got on for a little each day, you have more than enough time. Don't complain about not being able to get into teams because you didn't take the little time required to get the weapon.
