If you have not played with Yoda in a rated setting then, sure, I could see being skeptical of his abilities, but I know the last time he helped us out and filled for us in rated in back to back novares he took the off node fram casual and ld-50. In the casual game the assassin was apparently being stupid or was out of position, but in the ld-50 game he 1 on 1 Ed for the node. But in both games his pressure was the game winner.
I don't want to be insulting but as a former reg-star, if you we're actually one you would have long ago been picked up by a legit rated guild. You have to realize that rated teams run a completely different system than pugs do in regards to prettymuch every aspect of play from positioning to healing.
I remember my first game with hostile was a novare vs casual and I died 15 times because I did not understand the difference between regs and ranks.
