Arena bug or am I THAT good?

Well since I am a grandmaster now I decided to start a character for arena. His name is Liam Spellcrafter lvl 13 sorcerer and he is pure PWNAGE :P He is a knight now and lately i have been paired up against level 25s and higher. Is this a bug? All I know is I have had to resort to wild bolting which i find shameful. Any opinions guys?
