No doesn't bother me, it shouldn't bother anyone really.
Lots of people buy and trade their prizes.
I mean I got into the game at wave 3, so I was never able to get some of the cool stuff, so I bought some (like getting the alt art cards. That's the collector in me)
I've won most of what I have since by playing, but even so, not everything was won, some things I bought because It was before I was playing, or I was unable to travel away to attend.
Sometimes people just get cool extras when buying someones collection. I've seen that before too.
Where I'm at I have to travel out of province for the closest xwing scene, so that can be troublesome at times.
Sometimes buying what I want on eBay is cheaper than the travel costs.
However the downside of that is not getting to play xwing, which is why I really like going over. Great bunch over there.
