Wearing a flawless emblem or any other "hey, look at me, I did this" is very cheesy and laughable after the first two weeks that event dropped including raids. Saying all of the above, wear/equip whatever you want whenever you can. It's just a game, but know this, people will make fun of you (as they should) when you don't produce. It's like printing your own college degree when you didn't go there.
