Sorry but you're wrong. Go look at any log sites like WL.
Arms is superior on every fight at the moment. Single target, cleave, it doesn't matter. You're the one misinformed.
Agree with Andy, its not even up for debate. Simple maths, logs and a majority of peoples experience is that Arms, with the gear that drops in HM and with the given fight lengths/number of adds/exe range it is better in every situation.
BRF will be a different story though, and with ppl crying about the blue post saying they will nerf arms again... Are you new to worriors? If you play a warrior you have to become comfortable with the fact that your class will have many-many changes throughout the xpac like every other xpac before it!
Annnnd still waiting for update
