Is there a Cap on Area of Effect Radius?

I guess it'd work that way with skills like Cleave or Sweep, but for those single target, with AoE as a bonus like Infernal Blow, it might not be the same :3..

and it go even weirder with Reave, which AoE seems to start from the point of hit... maybe.

Weapon range affects Melee Splash radius. And coupled with Increased AoE that weapon range gets increased ALSO, making weapon range pretty effective at increaseing splash radius :D
