A few questionsFollow

First off, I would like to thank the veterans on this board. I've read the stickies and many posts in this forum and its helped me out a bunch!


I have a 60 war. Due to PC issues, I had to stop playing WoW right before BC came out. I'm going to be starting back up really soon and I decided to look into things to see how the game has changed. I was a 2 hand MS build, and the idea of keeping that but adding SS and Flurry sounds very appealing to me. I looked into the stickies for ideas and this is what I came up with.

This is NOT a "rate my build" post. I did take the time to look through stickies, but I had a few questions

1) Should I have more/less points in Iron Will?
2) Would my points in Improved Cleave, Piercing Howl, and Commanding Presence be better spent elsewhere?
3) Is 5/5 Flurry worth the trouble as a 2 hand MS spec?


Once again, I looked through the stickies and I'd just like some opinions from you guys. Thank you for taking the time to look at this!
