Guild Wars 2

Hi guys.. i have been farming skins for dungeon collections these last few days.. and today i start arah track and it seemed awfully slow to me.. 2 wins and i didnt even cross the halfpoint. It was very fishy, so I decided to do some detective work.. hopefully someone can shed some light on this

I though it was about 5000 per tier, each box being 1000. I could be wrong, haven’t personally tried to calculate it.
