I know that slow one hand weapons were viable prior to 4.0.1 for a Warrior but you would lose threat due to less heroic strike spam. However, with the changes to heroic strike, I'm really thinking about using a slow one hander just to see how it would go. I'm not really going to lose much in the way of defensive stats with the removal of def so that would also help.
Any other warriors already doing this? If so, how's it going?
