Recomand Me a Gem

Hi,
I want to use a new gem, green or blue socket with attack speed (I mean, not cast)
I use 1 axe and 1 Mace.
And i would like somehing strong maybe and I attack with it frontal... (Ex.: Shock nova is ok, viper strike)
(soory for bad english, i am really tired)

Shock nova is casted so we can toss that right out. One axe and one mace, hmmmm, not ideal there. The only one I can think of his dual strike. If you swap the mace for an axe or a sword then cleave is a nice option.

Edit: molten strike will work fine as well.

You could try Reave (green gem). It's good for AOE.

Try Frenzy for single target damage.
