Cleave Vs Ground Slam Vs Sweep (2H)

Trying to compare these 3 skills when using a 2H Weapon, sorry if its been asked before. Not only just the skills themselves but how they are effected by atk spd and AoE area increase.

Cleave
70% effective, 3%dmg/lvl, 180 arc. Medium Range*.
Qual=atk spd

Ground Slam
70% effective, 4%dmg/lvl, 90 arc. Long Range*. Added stun chance.
Qual=Stun Duration

Sweep
75% effective, 3%dmg/lvl, 360 arc. Short Range*.
Qual=Atk Spd

*Unsure on the ranges, just a guess really :P

Reasonably new to the game and I asked in global bout these questions but there seem to be conflicting answers.
Aside from the obvious differences in the skills they all seem to be basically the same, just with some small differences. As I said above the main thing I'm looking to learn is how they are each effected by bonuses to attack speed and increased AoE area/radius, the wiki is a little spotty and I'd rather not spend points and regret it later.

If anyone has some light to shed on the topic would be greatly appreciated.

Also, one more question, do weapons have range in this game like in D2. 2h'er have a longer reach then 1h'ers ect?

Cleave is out if you are using Maces.

Sweep has more of a ~300 or 330 degree radius, not full circle.

Sweep has been changed to a 360 arc.

I've made the choice to go with maces. So cleave is out.

From what I understand the AoE increased area buffs effect both Sweep and Ground Slam, but does it change the shape of the Ground Slam cone or just the radius?

Also the attack speed of Sweep is a bit strange cause of its animation, anyone have any info about that?

Increase AOE seems to lengthen AND widen the cone. This is anecdotal from personal experience, but it looks that way to me.

All depends what att. speed mace you got, what mobs you have at map, and what resist you got :)
When i find this one
i usually use "Sweep" now, but like i say when i see hard punch, or freezing mobs i cant use Sweep + Leap Slam because i can die after i use anything :)
Sometimes i only use "Leap Slam" and i think can be use for main skill AOE, but only when you have good att. speed mace like mine, or use att. speed gem (rrrg) or (rrrrg :p)
So... My proposition is use Leap Slam + Sweep and use Ground Slam if you Sweep cant make it.
