Why is it that the Devs keep placing these utterly WORTHLESS Enhancements into the Trees and then making them Pre-Reqs for something else?
Seriously...I'm not sure Vault {a quality of life enhancement itself} is even worth wasting AP on Staff Lunge! {Heck I'm not sure what if anything WOULD BE worth that!}.
Devs - We have Cleave, Great Cleave, Sweeping Strikes {Even with the super long cooldown}, Sly Flourish AND Quick Strikes - Staff Lunge is literally NEVER going to get used at it's current strength!}.
Sweeping Strikes should be a replacement for Great Cleave - With it's current cooldown it's an additional Cleave only {and really a replacement for Trip}.
