looking for 45 other players takes ages of time, if you dont want to duel every person with less than 90 base pts. I think most casual player dont have the time to search 45 worthy opponents, so they just defeat npcs and get their 3-4 platinum packs + 20k mgp anyway

in the end there are only two kind of people: tryhards aka wintrader and those who just beat npcs

only the utter minority will play the tournaments how they were intended to be, which gives no opportunity over beating npcs in the end
