I find it hard to believe that you'd get this attitude playing against the higher rated players in one of the DCT events, especially with any of the 3 players that you mentioned. Are you sure that you didn't overhear something out of context, or mistake some other behavior to mean that they didn't want you playing? I'd have an easier time seeing it if you mentioned some other players around here, but that seems out of character for the ones that you mentioned.
lower rated players are definately looked down upon (broad generalization) in phoenix. as the lowest rated player in the DCT events, I can agree with a lot that has been said. First time I played in a DCT I faced a higher rated player that was a complete ass towards me. didn't think he should have had to play me (and voiced that regularly to the other higher rated players). it happens ALL the time...
the other day i entered the 8 and under 10 ball at metro. when i signed up and told them i was a 5 rated player, they laughed at me and said "are you sure you want to play in a tournament like this?" i should have taken my money and gone somewhere else, but my ego and my pride made me say yes. i don't think i'll be playing there for a while.
i have been told i have to "earn my right" to play with the good players. that i shouldn't be able to walk in and pay a lower entry to play against people like mitch ellerman and tres kane and nick deleon...(2 of those guys didn't say that btw...but 1 did) but i disagree.
tournaments need people like me to play if they want to succeed. you need to expand your horizons and get your heads out of the dark, seedy pool halls you are used to and see what it's like in today's world. this isn't the 70's or the 80's...the color of money isn't what's big right now...wake up and welcome the newer, lower rated players...
