the bad thing about requiring players to player at cerain events in the prize money. in tier 1's the lower ranked players would always lose 1st or 2nd round and not earn enough. whereas if they're not required they can go to an event where they have a good chance in winning or going deep into it and earn the amount they need. i think this happens with young players sometimes. young players try to play the big events but they eventually have to play some lower tier events so they can get enough money to what they need to do.
