I remember the times in wotlk when it was REALLY hard to convince other players that ferals don't need hit cap.
Now its hard to convince some players that hit cap is actually valid
But even if its not. It does not matter. Feral rotation is not the easiest in the game. For new feral(like topic starter) it will be easier to keep rotation and than master it with hit/exp cap.
He will lose more dps because of unlucky misses and dodges than he will gain from theoretical dps increase without caps.
