Is Cleave Viable?

I use cleave because I wanted to make a 2H sword marauder. Cleave feels weak compared to other skills, but does the job.

Can't wait to get hands on new skills for 2H swords, it's just a question about time before they're released!

I don't see how Cleave is weak...using Lightning Strike gives u only 5 projectiles which is weird... using GS, well I hate hammers so not an option.... Cleave on the other hand gives u wide AoE with right gems. Say if ur doing dungeon, u gather the whole room then get into the corner and Cleave away.
