Maybe you are seeing it on a bad way.
juts analyze, if there is garm card in donation npc, it would be easier to have it than to mvp garm.
there is no guarantee that you'll get a card after killing garm, right?? and the fact that many people
are hunting it, there is a big competition among the community. After the garm event, i would say
that it is not enough, because still the demand of others for garm card is still getting higher as days passess.
Even i, im trading my str belt for 2 garm card and still no one sells it.
sorry if i may sound so rude but im just explaining my side.
hope you'll understand....
