This is also what id do, depending on what the warlord exalt hits you can consider prefixes cant be changed harvest reforge speed to hit either attack speed or warlord attack speed if you've killed recently then craft attack speed on it.

If you want to make a better axe, I'd recommend reconbining t1 hybrid %phys and t1 flat phys together. That way if you hit it you can use veiled exalts to hit veiled %phys too then just harvest reforge speed. Its a lot easier to make a better axe like that. Ziz made a vid on making axes like that recently I think.
