would you notice if your warrior is doing 90 or 120 dps? i find a really big difference when i hit the str warr play style. I can ask the same thing this way:
would you notice if your MONK was doing 250 or 280 DPS? I daresay you would. We are just accustomed to not giving tanks credit for that. If you have the gear, play the strength it is more worthwhile than you may think.
Remember though, the FoTM is not the way to go. What I'm trying to say is don't listen to me or anyone because we told you to. Do what you feel is the best way to play, and you will have optimized you and your classes potential. Even if it may not be all that high. :P
