I'm one of those guys. I kept my Imperial Assembly subscription running just in case I would need a good promo. I purchased three copies of Prayers and Blessings for twenty dollars a pop back in the day. I would get ninja friends for Gencon promos and if all I got from a Kotei was a new power card I was happy.
Obviously all of this, on top of chasing normal rares left a bad taste in my mouth (which is why I was clamoring for an L5R LCG for the past couple of years)
Luckily all that is gone now, I'm familiar with the way FFG runs events and the promos for prizes and participation are just alternate art of cards you can get in the regular box
I'm very grateful for that
