Well they are high value because lets be honest the majority of players are going to do their best to grind them out. Most players want them, so they are a reward that provides incentive to do something in game after hitting level 100. Im not saying I have an issue with people getting these rewards. Im saying that there is an issue with How people are getting them.
It might not effect you in the slightest right now, but as the playerbase dwindles, and less players spend time in pubs over private matches, the population of the game will continue to deteriorate. so while some player buying a shader or listening to a recording doesnt effect you, me, or anyone but them. The way they get that veritanium and those recordings matters. And the way they get them does effect each and every single one of us.
